title: Invoke method by MethodInfo
body: <p>I want to invoke methods with a certain attribute.
  So I'm cycling through all the assemblies and all methods to find the methods with my attribute. Works fine, but how do I invoke a certain method when I only got it's MethodInfo.</p>
  
  <pre><code>AppDomain app = AppDomain.CurrentDomain;
  Assembly[] ass = app.GetAssemblies();
  Type[] types;
  foreach (Assembly a in ass)
  {
      types = a.GetTypes();
      foreach (Type t in types)
      {
          MethodInfo[] methods = t.GetMethods();
          foreach (MethodInfo method in methods)
          {
              // Invoke a certain method
          }
      }
  }
  </code></pre>
  
  <p>The problem is that I don't know the instance of the class that contains that certain method. So I can't invoke it properly because the methods are not static.
  I also want to avoid creating a new instance of this class if possible.</p>
