C#: how to get an object by the name stored in String?

Question

is it possible in C# to get an object by name?

i.e. get this.obj0 using

string objectName = \"obj0\";
executeSomeFunctionOnObject(this.someLoadObject

You can't access an object by name. Using reflection, though, you can all fields and properties of a class (by name, if you want). If your object is stored in a field level variable or in a property, then this will give you what you want:

Type myType = typeof(MyClass);
FieldInfo[] myFields = myType.GetFields(BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.Public);

PropertyInfo[] myproperties = myType.GetProperties(BindingFlags.NonPublic | BindingFlags.Instance | BindingFlags.Public);

You can also call GetField and GetProperty (singular) and pass in a string to have it return a single member matching that name (make sure to check for null).
