我正在加载一个 dll,创建一个实例并想要调用方法并检查返回值。创建实例时出现异常 {"Parameter count mismatch."}:
static void Main(string[] args)
{
ModuleConfiguration moduleConfiguration = new ModuleConfiguration();
// get the module information
if (!moduleConfiguration.getModuleInfo())
throw new Exception("Error: Module information cannot be retrieved");
// Load the dll
string moduledll = Directory.GetCurrentDirectory() + "\\" +
moduleConfiguration.moduleDLL;
testDLL = Assembly.LoadFile(moduledll);
// create the object
string fullTypeName = "MyNameSpace."+ moduleConfiguration.moduleClassName;
Type moduleType = testDLL.GetType(fullTypeName);
Type[] types = new Type[1];
types[0] = typeof(string[]);
ConstructorInfo constructorInfoObj = moduleType.GetConstructor(
BindingFlags.Instance | BindingFlags.Public, null,
CallingConventions.HasThis, types, null);
if (constructorInfoObj != null)
{
Console.WriteLine(constructorInfoObj.ToString());
constructorInfoObj.Invoke(args);
}
The constructor for the class in dll is:
public class SampleModule:ModuleBase
{
/// <summary>
/// Initializes a new instance of the <see cref="SampleModule" /> class.
/// </summary>
public SampleModule(string[] args)
: base(args)
{
Console.WriteLine("Creating SampleModule");
}
问:1.我做错了什么?2. 如何获取方法、调用它并获取返回值?3. 有没有更好的方法来做到这一点?
