How to Compare two Stringsand to copy string into other string using C# Code. What is the syntax? Is there any system defined function such as strcmp,strcpy as used in C I am taken two values in strings , now I want to compare which one is greater. I can do it treating values as int or to convert.ToInt32, but requirement is to treat and compare them as strings.

To compare 2 strings, you could use the String.Compare method. To copy one string value into another, all you do is string oldValue = "OldValue"; string newValue = oldValue;

There are several ways you can compare strings in C#. The simplest way is to just test using equality:

string a = "This is a test";
string b = "This is another test";

if (a == b) {
// do something
}

However, this will do a case-sensistive, culture-sensitive compare which may not be what you want and isn't necessarily the most performant test. The closest methods to strcmp in C# are going to be the String.Compare, String.CompareOrdinal or the String.CompareTo methods. In order to copy a string, you can simply copy it. Strings in C# are immutable, so you will always get a new instance of the string:

string a = "This is a test";
string b = a;

You can find all of the string methods here[^].
