Gets whether the specified Uri is a universal naming convention (UNC) path.
Assembly: System (in System.dll)
The property is true if the specified Uri instance is a UNC path (such as \\server\folder or file://server/folder). This property always returns true if the URI has the file:// scheme and specifies a host component.
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:
The AbsolutePath is /download/file.ext.
The Host property is equal to: computer.
The 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:
The AbsolutePath property is //computer/download/file.ext.
The Host property is an empty string.
The property is false.
The LocalPath property is computer/download/file.ext.
The following example creates a Uri instance and determines whether it is a UNC path.
Dim uriAddress2 As Uri = New Uri("file://server/filename.ext") outputBlock.Text &= uriAddress2.LocalPath outputBlock.Text &= vbCrLf If uriAddress2.IsUnc Then outputBlock.Text &= "Uri is a UNC path" outputBlock.Text &= vbCrLf Else outputBlock.Text &= "Uri is not a UNC path" outputBlock.Text &= vbCrLf End If
