Generic Method Executed with a runtime type [duplicate]

Question

I have the following code:

 public class ClassExample {      void DoSomthing<T>(string name, T value)     {         SendToDatabase(name, value);     }      public class ParameterType     {         public readonly string Name;         public readonly Type DisplayType;         public readonly string Value;          public ParameterType(string name, Type type, string value)         {             if (string.IsNullOrEmpty(name))                 throw new ArgumentNullException("name");             if (type == null)                 throw new ArgumentNullException("type");              this.Name = name;             this.DisplayType = type;             this.Value = value;         }     }      public void GetTypes()     {         List<ParameterType> l = report.GetParameterTypes();          foreach (ParameterType p in l)         {             DoSomthing<p.DisplayType>(p.Name, (p.DisplayType)p.Value);         }      } } 

Now, I know I cannot perform DoSomething() is there any other way to use this function?

Answer 1

You can, but it involves reflection, but you can do it.

typeof(ClassExample)     .GetMethod("DoSomething")     .MakeGenericMethod(p.DisplayType)     .Invoke(this, new object[] { p.Name, p.Value }); 

This will look at the top of the containing class, get the method info, create a generic method with the appropriate type, then you can call Invoke on it.

Answer 2

this.GetType().GetMethod("DoSomething").MakeGenericMethod(p.Value.GetType()).Invoke(this, new object[]{p.Name, p.Value}); 

Should work.
