Assembly: mscorlib (in mscorlib.dll)
The method returns a String object that has the same value as the original string but represents a different object reference. It differs from an assignment operation, which assigns an existing string reference to an additional object variable. The example illustrates the difference.
The following example creates two string objects with different values. When it calls the method to assign the first value to the second string, the output indicates that the strings represent different object references although their values are now equal. On the other hand, when the first string is assigned to the second string, the two strings have identical values because they represent the same object reference.
