我有例外：操作可能會破壞運行時，我不知道爲什麼:(請幫我如何從單調用實例方法與EMIT
我加了本地，但仍然沒有工作......
。方法要動態創建（REF000001）：
public static int REF000001(int REF000002, object REF000003, DateTime REF000004)
{
return (int)typeof(REF000005).GetMethod("REF000006", new Type[] { typeof(int), typeof(object), typeof(DateTime) }).Invoke(REF000005.REF000008(), new object[] { REF000002, REF000003, REF000004 });
}
這是類，我想從單調用方法
3210 。從ILDASM返回：

object REF000003,

它看起來像你忘了[聲明你的本地變量]（http://msdn.microsoft.com/en-us/library/y1xffef4.aspx）。 – svick
我添加本地，並更改我的代碼，但仍然無法正常工作。請你幫我一下。 – user2807597
