Uri.ToString Method

Gets a canonical string representation for the specified Uri instance.

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

[SecurityPermissionAttribute(SecurityAction.InheritanceDemand, Flags = SecurityPermissionFlag.Infrastructure)]
public override string ToString()

Return Value

Type: System.String
A String instance that contains the unescaped canonical representation of the Uri instance. All characters are unescaped except #, ?, and %.

The string returned by this method does not contain port information when the port is the default port for the scheme.

NoteNote:

The string returned by the ToString method may contain control characters, which can corrupt the state of a console application. You can use the GetComponents method with the UriFormat.SafeUnescaped format to remove control characters from the returned string.

The following example creates a new Uri instance from a string. It illustrates the difference between the value returned from OriginalString, which returns the string that was passed to the constructor, and from a call to ToString, which returns the canonical form of the string.

// 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.
Uri* uriAddress = new Uri(S"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); 

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