Question

class CFoo 
{
       private string _filePathFormatString;

       public string Foo()
       {
            System.Threading.Thread.VolatileRead(ref _filePathFormatString);
            ...
       }   
}

string is object, why this VolatileRead doesn’t compile?
I think it should match VolatileRead(ref object) signature.

Answer 1

Types of formal and actual parameters must be exactly the same if you pass parameter with “ref” in C#. So you can change field to be type of object. Second way to do it might be using ReaderWriteLockSlim instead of volatile read.
