Uri.IsUnc Property
.NET Framework (current version)
Gets whether the specified Uri is a universal naming convention (UNC) path.
Assembly: System (in System.dll)
| Exception | Condition |
|---|---|
| InvalidOperationException | This instance represents a relative URI, and this property is valid only for absolute URIs. |
The IsUnc 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.
The following example creates a Uri instance and determines whether it is a UNC path.
Dim uriAddress2 As New Uri("file://server/filename.ext")
Console.WriteLine(uriAddress2.LocalPath)
Console.WriteLine("Uri {0} a UNC path", IIf(uriAddress2.IsUnc, "is", "is not")) 'TODO: For performance reasons this should be changed to nested IF statements
Console.WriteLine("Uri {0} a local host", IIf(uriAddress2.IsLoopback, "is", "is not")) 'TODO: For performance reasons this should be changed to nested IF statements
Console.WriteLine("Uri {0} a file", IIf(uriAddress2.IsFile, "is", "is not")) 'TODO: For performance reasons this should be changed to nested IF statements
