Question

I definitely remember seeing somewhere an example of doing so using reflection or something. It was something that had to do with SqlParameterCollection which is not creatable by a user (if I’m not mistaken). Unfortunately cannot find it any longer.

Can anyone please share this trick here? Not that I consider it a valid approach in development, I’m just very interested in the possibility of doing this.

// the types of the constructor parameters, in order // use an empty Type[] array if the constructor takes no parameters Type[] paramTypes = new Type[] { typeof(string), typeof(int) };  // the values of the constructor parameters, in order // use an empty object[] array if the constructor takes no parameters object[] paramValues = new object[] { 'test', 42 };  TheTypeYouWantToInstantiate instance =     Construct<TheTypeYouWantToInstantiate>(paramTypes, paramValues);  // ...  public static T Construct<T>(Type[] paramTypes, object[] paramValues) {     Type t = typeof(T);      ConstructorInfo ci = t.GetConstructor(         BindingFlags.Instance | BindingFlags.NonPublic,         null, paramTypes, null);      return (T)ci.Invoke(paramValues); }
