Constructors
SharArchive()
Initializes a new instance of the Aspose.Zip.Shar.SharArchive class.
public SharArchive()Examples
The following example shows how to compress a file.
using (var archive = new SharArchive())
{
archive.CreateEntry("first.bin", "data.bin");
archive.Save("archive.shar");
}SharArchive(string)
Initializes a new instance of the Aspose.Zip.Shar.SharArchive class prepared for decompressing.
public SharArchive(string path)Parameters
path string
Path to the source of the archive.
Exceptions
path is null.
The caller does not have the required permission to access.
The path is empty, contains only white spaces, or contains invalid characters.
Access to file path is denied.
The specified path, file name, or both exceed the system-defined maximum length. For example, on Windows-based platforms, paths must be less than 248 characters, and file names must be less than 260 characters.
File at path contains a colon (:) in the middle of the string.
The file is not found.
The specified path is invalid, such as being on an unmapped drive.
The file is already open.
Properties
Entries
Gets entries of Aspose.Zip.Shar.SharEntry type constituting the archive.
public ReadOnlyCollection<sharentry> Entries { get; }Property Value
ReadOnlyCollection < SharEntry >
Methods
CreateEntries(string, bool)
Adds to the archive all the files and directories recursively in the directory given.
public SharArchive CreateEntries(string sourceDirectory, bool includeRootDirectory = true)Parameters
sourceDirectory string
Directory to compress.
includeRootDirectory bool
Indicates whether to include the root directory itself or not.
Returns
Shar entry instance.
Examples
using (FileStream sharFile = File.Open("archive.shar", FileMode.Create))
{
using (var archive = new SharArchive())
{
archive.CreateEntries("C:\folder", false);
archive.Save(sharFile);
}
}Exceptions
sourceDirectory is null.
The caller does not have the required permission to access sourceDirectory.
sourceDirectory contains invalid characters such as “, <, >, or |.
The specified path, file name, or both exceed the system-defined maximum length. For example, on Windows-based platforms, paths must be less than 248 characters, and file names must be less than 260 characters. The specified path, file name, or both are too long.
sourceDirectory stands for a file, not for a directory.
Archive has been disposed and cannot be used.
CreateEntries(DirectoryInfo, bool)
Adds to the archive all the files and directories recursively in the directory given.
public SharArchive CreateEntries(DirectoryInfo directory, bool includeRootDirectory = true)Parameters
directory DirectoryInfo
Directory to compress.
includeRootDirectory bool
Indicates whether to include the root directory itself or not.
Returns
Shar entry instance.
Examples
using (FileStream sharFile = File.Open("archive.shar", FileMode.Create))
{
using (var archive = new SharArchive())
{
archive.CreateEntries(new DirectoryInfo("C:\folder"), false);
archive.Save(sharFile);
}
}Exceptions
directory is null.
The caller does not have the required permission to access directory.
directory stands for a file, not for a directory.
Archive has been disposed and cannot be used.
CreateEntry(string, FileInfo, bool)
Create a single entry within the archive.
public SharEntry CreateEntry(string name, FileInfo fileInfo, bool openImmediately = false)Parameters
name string
The name of the entry.
fileInfo FileInfo
The metadata of file or folder to be compressed.
openImmediately bool
True, if open the file immediately, otherwise open the file on archive saving.
Returns
Shar entry instance.
Examples
FileInfo fileInfo = new FileInfo("data.bin");
using (var archive = new SharArchive())
{
archive.CreateEntry("test.bin", fileInfo);
archive.Save("archive.shar");
}Remarks
If the file is opened immediately with openImmediately parameter it becomes blocked until archive is disposed.
Exceptions
name is null.
name is empty.
fileInfo is null.
Archive has been disposed and cannot be used.
CreateEntry(string, string, bool)
Create a single entry within the archive.
public SharEntry CreateEntry(string name, string sourcePath, bool openImmediately = false)Parameters
name string
The name of the entry.
sourcePath string
Path to file to be compressed.
openImmediately bool
True, if open the file immediately, otherwise open the file on archive saving.
Returns
Shar entry instance.
Examples
using (var archive = new SharArchive())
{
archive.CreateEntry("first.bin", "data.bin");
archive.Save("archive.shar");
}Remarks
The entry name is solely set within name parameter. The file name provided in sourcePath parameter does not affect the entry name.
If the file is opened immediately with openImmediately parameter it becomes blocked until archive is disposed.
Exceptions
sourcePath is null.
The caller does not have the required permission to access.
The sourcePath is empty, contains only white spaces, or contains invalid characters. - or - File name, as a part of name, exceeds 100 symbols.
Access to file sourcePath is denied.
The specified sourcePath, file name, or both exceed the system-defined maximum length. For example, on Windows-based platforms, paths must be less than 248 characters, and file names must be less than 260 characters. - or - name is too long for shar.
File at sourcePath contains a colon (:) in the middle of the string.

CreateEntry(string, Stream)
Create a single entry within the archive.
public SharEntry CreateEntry(string name, Stream source)Parameters
name string
The name of the entry.
source Stream

public SharArchive DeleteEntry(SharEntry entry)Parameters
entry SharEntry

Here is how you can remove all entries except the last one:

archive.Save(outputSharFile);
}Exceptions
entry is null.
Archive has been disposed and cannot be used.
DeleteEntry(int)

entryIndex int
The zero-based index of the entry to remove.
Returns
The archive with the entry deleted.
Examples
using (var archive = new SharArchive("two_files.shar"))

Dispose(bool)
Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.

Dispose()
Performs application-defined tasks associated with freeing, releasing, or resetting unmanaged resources.
public void Dispose()Save(string)
Saves archive to a destination file provided.
public void Save(string destinationFileName)Parameters
destinationFileName string
The path of the archive to be created. If the specified file name points to an existing file, it will be overwritten.
Examples
using (var archive = new SharArchive())
{
archive.CreateEntry("entry1", "data.bin");
archive.Save("archive.shar");
}Remarks
It is possible to save an archive to the same path as it was loaded from. However, this is not recommended because this approach uses copying to a temporary file.
Exceptions
destinationFileName is a zero-length string, contains only white space, or contains one or more invalid characters as defined by System.IO.Path.InvalidPathChars.
destinationFileName is null.
The specified destinationFileName, file name, or both exceed the system-defined maximum length. For example, on Windows-based platforms, paths must be less than 248 characters, and file names must be less than 260 characters.
The specified destinationFileName is invalid, (for example, it is on an unmapped drive).
An I/O error occurred while opening the file.
destinationFileName specified a file that is read-only and access is not Read.-or- path specified a directory.-or- The caller does not have the required permission.
destinationFileName is in an invalid format.
The file is not found.
Archive has been disposed and cannot be used.
Save(Stream)
Saves archive to the stream provided.
public void Save(Stream output)Parameters
output Stream
Destination stream.
Examples
using (FileStream sharFile = File.Open("archive.shar", FileMode.Create))
{
using (var archive = new SharArchive())
{
archive.CreateEntry("entry1", "data.bin");
archive.Save(sharFile);
}
}Remarks
output must be writable.
