How can we identify partial classes in C#?

Answer:

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!
