How do i fix 'the best overloaded method match for 'x' has some invalid arguments' in c#?

This error indicates that a method is called with incorrect argument types.

Example:

public void MyMethod(int a) { }
...
MyMethod("string argument");

Solution:

public void MyMethod(int a) { }
...
MyMethod(123);

Ensure that you're passing arguments of the correct type to your methods.
