What are the rules for naming classes in C#?

A class definition starts with the keyword class followed by the class name; and the class body enclosed by a pair of curly braces.

The following is the syntax −

<access specifier> class class_name {
   // member variables
   <access specifier> <data type> variable1;
   <access specifier> <data type> variable2;
   ...
   <access specifier> <data type> variableN;
   // member methods
   <access specifier> <return type> method1(parameter_list) {
      // method body
   }

   <access specifier> <return type> method2(parameter_list) {
   // method body
   }

   ...
   <access specifier> <return type> methodN(parameter_list) {
      // method body
   }
}
