[JScript]
public function Clone() : Object;

Return Value

This instance of String.

Implements

ICloneable.Clone

Remarks

The return value is not an independent copy of this instance; it is simply another view of the same data. Use the Copy or CopyTo method to create a separate String object with the same value as this instance.

Example

[C#, C++] The following simple code example demonstrates the Clone method.

[C#] 
// Create a Unicode String with 5 Greek Alpha characters
String szGreekAlpha = new String('\u0319',5);
// Create a Unicode String with a Greek Omega character
String szGreekOmega = new String(new char [] {'\u03A9','\u03A9','\u03A9'},2,1);

String szGreekLetters = String.Concat(szGreekOmega, szGreekAlpha, szGreekOmega.Clone());

// Examine the result
Console.WriteLine(szGreekLetters);

// The first index of Alpha
int ialpha = szGreekLetters.IndexOf('\u0319');
// The last index of Omega
int iomega = szGreekLetters.LastIndexOf('\u03A9');

Console.WriteLine("The Greek letter Alpha first appears at index " + ialpha +
    " and Omega last appears at index " + iomega + " in this String.");

[C++] 
// Create a Unicode String with 5 Greek Alpha characters
String* szGreekAlpha = new String(L'\x0319',5);
// Create a Unicode String with a Greek Omega character
wchar_t charArray5 [3] = {L'\x03A9',L'\x03A9',L'\x03A9'};
String* szGreekOmega = new String( charArray5 ,2,1);

String* szGreekLetters = String::Concat(szGreekOmega, szGreekAlpha, szGreekOmega->Clone());

// Examine the result
Console::WriteLine(szGreekLetters);

// The first index of Alpha
int ialpha = szGreekLetters->IndexOf(L'\x0319');
// The last index of Omega
int iomega = szGreekLetters->LastIndexOf(L'\x03A9');

Console::WriteLine(String::Concat("The Greek letter Alpha first appears at index ",Convert::ToString(ialpha) ));
Console::WriteLine(String::Concat(" and Omega last appears at index ", Convert::ToString(iomega), " in this String."));
