shift right operator on strings in c#

I have a stream reader object "file" and a character type variable "hex"

System.IO.StreamReader file = new System.IO.StreamReader(filename);

char[] hex=new char[20];
int @base;

the code i want to implement is 

        string line;
       while ((line=file.ReadLine()) != null) //Reading each address from trace file
        {

            if (@base != 10)
            {          
               line >> hex;  
                 ///this line giving errors, as shift right cannot be implemented on string types
                address = changebase(hex, @base);

            }
            else
                line >> address;

I am making a cache memory hit and miss project. But in c# shift right cannot be applied to string variables, so any other option to implement the line of code .. Please any help

Any other way to implement this line

In C# you can only overload the operators << and >> when one of the operands is an int, so this type of code is strictly off limits.

Reference:

User-defined types can overload the >> operator; the type of the first operand must be the user-defined type, and the type of the second operand must be int. For more information, see operator.

The reason why you cannot do this is because the language designers did not want you to, and I certainly can't fault them. line >> hex might look cool, but it does the same thing as line.Insert(hex) and is usually much less descriptive of what actually happens.
