Get the list of method names from the C# class

Sometimes we come across a requirement to get list of methods in C# class. This is very useful if you want to automate your documentation process and want to have a list of methods in a class.

To get the list of methods in class you normally use the GetMethods method. This method will return an array of MethodInfo objects. We have a lot of information about a method in the MethodInfo object and the name is one of them.

Type.GetMethods

You can use BindingFlags to get a filtered list of methods. For example, if you want to get only Public methods in class you can write code like

MethodInfo[] mInfos = typeof(MyClass).GetMethods(BindingFlags.Public);

There are four types of binding flags

• Public
• Static
• NonPublic
• Instance

BindingFlags and MethodInfo enumerations are part of System.Reflaction namespace.

Example: Let’s assume you want to get the names of all public and static methods in a class.

MethodInfo[] mInfos = typeof(MyTestClass).GetMethods(BindingFlags.Public |
BindingFlags.Static);
Array.Sort(mInfos,
delegate(MethodInfo methodInfo1, MethodInfo methodInfo2)
{ 
   return methodInfo1.Name.CompareTo(methodInfo2.Name); 
});

Now let’s write names

foreach (MethodInfo mInfo in mInfos)
{
   Console.WriteLine(mInfo.Name);
}
