[edit] The C# this Operator
The this operator points to a class field member. In some situations it may be necessary to use the name of a field member. The only way to distinguish between the two is to use the this operator for the field member. Take a look at the following code:
using System;
class Program
{
public class test
{
public int MyAge;
public int MyMethod(int MyAge)
{
this.MyAge = MyAge;
++this.MyAge;
return this.MyAge;
}
}
static void Main()
{
test ClassObject = new test();
Console.WriteLine(ClassObject.MyMethod(18));
Console.Read();
}
}
Output:
19
As you can see the local variable in the MyMethod method is named MyAge. The field variable is named MyAge also. So how does the compiler suppose to distinguish between the two. Well, by using the this operator point to the field variable in the class.
If the this operator was not used the local variable in the method would be used.
