Java调用C# DLL传参数问题

我用Java调用别人的C#写的DLL参数类型一直不匹配

我的Java：
int[] commandArray = {2, 3, 4, 5};
Object objResult = Dispatch.call(dotnetCom,"DeviceWriteThenRead",commandArray).getVariant();
C# Dll函数是
public object DeviceWriteThenRead(object commandArray){
if (commandArray.GetType() != typeof(object[]))
{
throw new ArgumentException("Argument must be an array of integers");
}
object[] objArray = (object[]) commandArray;
.....
}

运行一直报错
Argument must be an array of integers

请问我java里面的commandArray 应该是什么类型？

Answer 1

object[] commandArray = {2, 3, 4, 5};

试试吧！
