In C#, Copy() is a string method. It is used to create a new instance of String with the same value for a specified String. The Copy() method returns a String object, which is the same as the original string but represents a different object reference. To check its reference, use assignment operation, which assigns an existing string reference to an additional object variable.
public static string Copy(string str)
Explanation : This method accepts single parameter str which is the original string to be copied. And it returns the string value, which is the new string with the same value as str. The type of Copy() method is System.String.
Example Program to illustrate the Copy() Method
Original Strings are str1 = 'GeeksforGeeks' and str2='GFG' After Copy method Strings are str1 = 'GeeksforGeeks' and str2='GeeksforGeeks' ReferenceEquals: False Equals: True After Assignment Strings are str1 = 'GeeksforGeeks' and str2 = 'GeeksforGeeks' ReferenceEquals: True Equals: True
