Uri.ToString 方法

public:
 override System::String ^ ToString();

public override string ToString();

override this.ToString : unit -> string

Public Overrides Function ToString () As String

傳回

這個實例無法逃脫的經典表徵 Uri 。 除了#、？和 %外，所有角色都無法逃脫。

範例

以下範例是從字串建立一個新 Uri 實例。 它說明了從 OriginalString返回的值（回傳給建構子的字串）與從呼叫 返回 ToString字串的典範形式的差異。

// Create a new Uri from a string address.
Uri uriAddress = new Uri("HTTP://www.Contoso.com:80/thick%20and%20thin.htm");

// Write the new Uri to the console and note the difference in the two values.
// ToString() gives the canonical version.  OriginalString gives the orginal
// string that was passed to the constructor.

// The following outputs "http://www.contoso.com/thick and thin.htm".
Console.WriteLine(uriAddress.ToString());

// The following outputs "HTTP://www.Contoso.com:80/thick%20and%20thin.htm".
Console.WriteLine(uriAddress.OriginalString);

// Create a new Uri from a string address.
let uriAddress = Uri "HTTP://www.Contoso.com:80/thick%20and%20thin.htm"

// Write the new Uri to the console and note the difference in the two values.
// ToString() gives the canonical version.  OriginalString gives the orginal
// string that was passed to the constructor.

// The following outputs "http://www.contoso.com/thick and thin.htm".
printfn $"{uriAddress.ToString()}"

// The following outputs "HTTP://www.Contoso.com:80/thick%20and%20thin.htm".
printfn $"{uriAddress.OriginalString}"

    ' Create a new Uri from a string address.
    Dim uriAddress As New Uri("HTTP://www.Contoso.com:80/thick%20and%20thin.htm")
    
    ' Write the new Uri to the console and note the difference in the two values.
    ' ToString() gives the canonical version.  OriginalString gives the orginal 
    ' string that was passed to the constructor.
    ' The following outputs "http://www.contoso.com/thick and thin.htm".
    Console.WriteLine(uriAddress.ToString())
    
    ' The following outputs "HTTP://www.Contoso.com:80/thick%20and%20thin.htm".
    Console.WriteLine(uriAddress.OriginalString)

End Sub
