What is an example of “this” assignment in C#?

Question

Does anybody have useful example of this assignment inside a C# method? I have been asked for it once during job interview, and I am still interested in answer

Answer 1

using the this keyword ensures that only variables and methods scoped in the current type are accessed. This can be used when you have a naming conflict between a field/property and a local variable or method parameter.

Typically used in constructors:

private readonly IProvider provider;
public MyClass(IProvider provider)
{
  this.provider = provider;
}

In this example we assign the parameter provider to the private field provider.
