如何多次调用Com对象“编辑” [英] How I Can Calling Com Object Multiple Time "Edited"

问题描述

我想用c＃调用matlab中的函数来循环使用com组件

当我尝试它时我有这个例外



无效的被叫方。 （HRESULT异常：0x80020010（DISP_E_BADCALLEE））



这是代码

i want to call function in matlab from c# inside for loop using com component
when i tried it i had this exception

Invalid callee. (Exception from HRESULT: 0x80020010 (DISP_E_BADCALLEE))

this is the code

   public void Start()
        {
            var activationContext = Type.GetTypeFromProgID("matlab.application.single");
            var matlab = (MLApp.MLApp)Activator.CreateInstance(activationContext);
            matlab.Visible = 0;
            int index = 0;
            var feture = new double[10][];
            for (int j = 1; j < 8; j++)
            {
                object result1;
                string name = @"C:\Users\Eng\Documents\Visual Studio 2010\Projects\FinalProject\FinalProject\Matlab\" +
                              j + ".JPG";
                matlab.Feval("WBC_SegProposed", 6, out result1, name, 0, j);
                var res = (Array) result1;
                var myEnumerator = res.GetEnumerator();
                myEnumerator.MoveNext();
                var length = (double) myEnumerator.Current;
                var len = (int) length;
                myEnumerator.MoveNext();
                var area = (double[,]) myEnumerator.Current;
                myEnumerator.MoveNext();
                var perimeter = (double[,]) myEnumerator.Current;
                myEnumerator.MoveNext();
                var compactness = (double[,]) myEnumerator.Current;
                myEnumerator.MoveNext();
                var circularity = (double[,]) myEnumerator.Current;
                myEnumerator.MoveNext();
                var names = (object[,]) myEnumerator.Current;
}
}

此指令的例外是matlab.Feval（WBC_SegProposed，6，out result1，name，0，j ）;

我该怎么办？

the exception was for this instruction " matlab.Feval("WBC_SegProposed", 6, out result1, name, 0, j);"
what should i do ?
