String type in C #

In C #, the string type is actually the reference type. The String object is allocated to the stack instead of the stack. Therefore, when a string variable is assigned to another string, two references to the same string in memory are obtained. However, there are some differences between string and reference types in common operations. For example, strings cannot be changed. If you modify one of the strings, A New String object is created, and the other string does not change. Run the following code:

String A = "A1 ";

String B = "B" +;

Console. writeline ("B is:" + B );

A = "A2 ";

Console. writeline ("A is:" + );

Console. writeline ("B is:" + B );

Console. Read ();

 

 

Output result:

BA1

A2

BA1
