c# - Compact Framework - 如何动态创建没有默认构造函数的类型？

Question

我使用的是.NET CF 3.5。我想要创建的类型没有默认构造函数，因此我想将字符串传递给重载的构造函数。我该怎么做？

代码:

Assembly a = Assembly.LoadFrom("my.dll");
Type t = a.GetType("type info here");
// All ok so far, assembly loads and I can get my type

string s = "Pass me to the constructor of Type t";
MyObj o = Activator.CreateInstance(t); // throws MissMethodException

Answer 1

MyObj o = null;
Assembly a = Assembly.LoadFrom("my.dll");
Type t = a.GetType("type info here");

ConstructorInfo ctor = t.GetConstructor(new Type[] { typeof(string) });
if(ctor != null)
   o = ctor.Invoke(new object[] { s });
