Uri.IsLoopback Property


Gets whether the specified Uri references the local host.

Namespace:   System
Assembly:  System (in System.dll)

public bool IsLoopback { get; }

Property Value

Type: System.Boolean

A Boolean value that is true if this Uri references the local host; otherwise, false.

Exception Condition

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, 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.

Uri uriAddress2 =  new Uri("file://server/filename.ext");
Console.WriteLine("Uri {0} a UNC path", uriAddress2.IsUnc ? "is" : "is not");
Console.WriteLine("Uri {0} a local host", uriAddress2.IsLoopback ? "is" : "is not");
Console.WriteLine("Uri {0} a file", uriAddress2.IsFile ? "is" : "is not");
