        MsExcel.Range rng = MyExcelAppInstance.get_Range("A1:D4", Type.Missing);
        //Get a 2D Array of values from the range in one shot: 
        object[,] myArray = (object[,])rng.get_Value(Type.Missing);

        // Process 'myArray' however you want here. 
        // Note that the Array returned from Excel is base 1, not base 0. 
        // To be safe, use GetLowerBound() and GetUpperBound: 
        for (int row = myArray.GetLowerBound(0); row <= myArray.GetUpperBound(0); row++)
        {
            for (int column = myArray.GetLowerBound(1); column <= myArray.GetUpperBound(1); column++)
            {
                if (myArray[row, column] is double)
                {
                    myArray[row, column] = (double)myArray[row, column] * 2;
                }
            }
        }

        // Pass back the results in one shot: 
        rng.set_Value(Type.Missing, myArray);  // where gets an error

        return code + code;
    }

我收到一个错误“HRESULT 异常：0x800A03EC”。我尝试设置语言环境，但没有成功。没有 set_value，它工作正常。知道为什么这不起作用吗？

我曾经遇到过类似的问题，错误结果是由无效参数引起的（我以无效格式传递了范围字符串）。确保调用时范围和所有数组内容都有效set_Value。
