Gets a value that indicates whether the specified Uri is a universal naming convention (UNC) path.
public:
property bool IsUnc { bool get(); };public bool IsUnc { get; }member this.IsUnc : boolPublic ReadOnly Property IsUnc As BooleanProperty Value
true if the Uri is a UNC path; otherwise, false.
Exceptions
This instance represents a relative URI, and this property is valid only for absolute URIs.
Examples
The following example creates a Uri instance and determines whether it is a UNC path.
Uri^ uriAddress2 = gcnew Uri( "file://server/filename.ext" );
Console::WriteLine( uriAddress2->LocalPath );
Console::WriteLine( "Uri {0} a UNC path", uriAddress2->IsUnc ? (String^)"is" : "is not" );
Console::WriteLine( "Uri {0} a local host", uriAddress2->IsLoopback ? (String^)"is" : "is not" );
Console::WriteLine( "Uri {0} a file", uriAddress2->IsFile ? (String^)"is" : "is not" );
// The example displays the following output:
// \\server\filename.ext
// Uri is a UNC path
// Uri is not a local host
// Uri is a file
Uri uriAddress2 = new Uri("file://server/filename.ext");
Console.WriteLine(uriAddress2.LocalPath);
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");
// The example displays the following output:
// \\server\filename.ext
// Uri is a UNC path
// Uri is not a local host
// Uri is a file
let uriAddress2 = Uri "file://server/filename.ext"
printfn $"{uriAddress2.LocalPath}"
printfn $"""Uri {if uriAddress2.IsUnc then "is" else "is not"} a UNC path"""
printfn $"""Uri {if uriAddress2.IsLoopback then "is" else "is not"} a local host"""
printfn $"""Uri {if uriAddress2.IsFile then "is" else "is not"} a file"""
// The example displays the following output:
// \\server\filename.ext
// Uri is a UNC path
// Uri is not a local host
// Uri is a file
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
' The example displays the following output:
' \\server\filename.ext
' Uri is a UNC path
' Uri is not a local host
' Uri is a file
Remarks
The IsUnc property is true if the specified Uri instance is a UNC path (such as \\server\folder, //server, or file://server/folder). This property always returns true if the URI has the file:// scheme and specifies a host component.
