int

 arguments. The other takes 

double

arguments.

Let’s look at this program closely. First, notice that 

MyClass

 defines a public constructor 

and a number of public methods, including the overloaded 

Set( )

 method.

Inside

Main( )

, a 

Type

 object representing 

MyClass

 is obtained using this line of code:

Type t = typeof(MyClass); // get a Type object representing MyClass

Recall that 

typeof

 returns a 

Type

 object that represents the specified type, which in this case 

is

MyClass

.

Using

t

 and the Reflection API, the program then displays information about the methods 

supported by 

MyClass

. First, a list of the methods is obtained by the following statement:

MethodInfo[] mi = t.GetMethods();

Next, a 

foreach

 loop is established that cycles through 

mi

. With each pass, the return 

type, name, and parameters for each method are displayed by the following code:

// Display return type and name.

Console.Write("   " + m.ReturnType.Name +

              " " + m.Name + "(");

ParameterInfo[] pi = m.GetParameters();

for(int i=0; i < pi.Length; i++) {

  Console.Write(pi[i].ParameterType.Name +

  if(i+1 < pi.Length) Console.Write(", ");

}

In this sequence, the parameters associated with each method are obtained by calling
