Uri.IsLoopback Property
.NET Framework (current version)
Gets whether the specified Uri references the local host.
Assembly: System (in System.dll)
| Exception | Condition |
|---|---|
| InvalidOperationException | This instance represents a relative URI, and this property is valid only for absolute URIs. |
IsLoopback returns true if the URI specified when this instance was created was 127.0.0.1, loopback, or localhost, or if the URI did not specify host information (for example, file:///c:Dir/file.txt). All other URIs return false.
The following example creates a Uri instance and determines whether it references a local host.
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
