What will happen if we compile below C# code?

public const string status_deactive = null;

public void initialize_const_value()
{
status_deactive = "DD";
}

When we compile above C# program,then it
will give compile-time error as

The left-hand side of an assignment must be a variable, property or indexer

Because constant values must be initialized in declaration only other than any where in the code.
