How can we identify partial classes in C#?

The class declaration with the keyword partial is denoting that the class is a partial class. Physically the partial classes can be available in different files/locations. The C# compiler treat them as a single class at the time of compilation.


        public partial class PartialClassExample
        {
            public void MethodOne(int input)
            {
                ///Do something.
            }
        }

        public partial class PartialClassExample
        {
            public string MethodTwo(string input)
            {
                return string.Format("Hello, {0}", input);
            }
        }


The PartialClassExample can be sit in different files but at the time of compilation they will be merged together.

Hope this helps!
