Uri.UriSchemeFile Field
Microsoft Silverlight will reach end of support after October 2021. Learn more.
Specifies that the URI is a pointer to a file. This field is read-only.
Namespace: System
Assembly: System (in System.dll)
Syntax
'Declaration
Public Shared ReadOnly UriSchemeFile As String
public static readonly string UriSchemeFile
Remarks
In .NET Framework version 1.1, a "file:///path" URI was translated to "file:/path". This has been corrected for version 2.0.
Silverlight-based applications are cross-platform, so they run in most modern Web browsers, including Apple Safari version 2.0 and later on Apple Mac OS X. However, full parsing for UNC style paths in a Uri is supported only on Windows. Any backslashes in a Uri for the UriSchemeFile representing a UNC path are converted to forward slashes on Apple Mac OS X.
An example that displays this issue is below:
Uri testUri = Uri(@"file://\\computer\download\file.ext");
On Windows, this UNC path is converted to the following Uri:
file://computer/download/file.ext
The AbsolutePath is /download/file.ext.
The Host property is equal to: computer.
The IsUnc property is true.
The LocalPath property is \\computer\download\file.ext.
On Apple Mac OS X, this UNC path is converted to the following Uri:
file::////computer/download/file.ext
The AbsolutePath property is //computer/download/file.ext.
The Host property is an empty string.
The IsUnc property is false.
The LocalPath property is computer/download/file.ext.
Examples
The following example creates a Uri instance and determines whether the scheme is UriSchemeFile.
Dim address4 As Uri = New Uri("file://server/filename.ext")
If address4.Scheme = Uri.UriSchemeFile Then
outputBlock.Text &= "Uri is a file"
outputBlock.Text &= vbCrLf
End If
Uri address4 = new Uri("file://server/filename.ext");
if (address4.Scheme == Uri.UriSchemeFile)
outputBlock.Text += "Uri is a file\n";
Uri address2 = new Uri("file://server/filename.ext");
if (address2.Scheme == Uri.UriSchemeFile)
Console.WriteLine("Uri is a file");
