Question

In C# you can refer to values in a class using the ‘this’ keyword.

class MyClass {     private string foo;      public string MyMethod()     {         return this.foo;     } } 

While I presume the answer will likley be user preference, is it best practice to use the this keyword within a class for local values?

Answer 1

In the spirit of DRY, I would say this is not a particularly useful practice in general. Almost any use of this can be shortened to an equivalent expression by just removing the this.

One exception is if you have a local parameter which happens to have the same name as another class member; in that case you must distinguish between the two with this. But this is a situation you can easily avoid, by simply renaming the parameter.
