C# COMException异常排除
C#引用Microsoft.Office.Interop.Excel.dll版本是15.0.0.0,我想用求逆矩阵,3阶和3阶以下都是正常的,和excel表格里求出来一样,官方说这个最大支持52阶矩阵,但是大于3阶就老出现这个异常,:
代码如下:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
namespace Matrix{
class Program
{
static void Main(string[] args)
{
// Object[,] a = new Object[3, 3] {{1,2,3},{4,5,6},{7,8,9} };
// Object[,] a = new Object[2, 2] { { 1, 2 }, { 4, 5 } };
Object[,] a = new Object[4, 4] { { 1, 2, 3, 4 }, { 4, 5, 6, 7 }, { 7, 8, 9, 10 }, { 1, 1, 1, 1 } };
getMInverse(a);
Console.ReadLine();
}
public static Object[,] getMInverse(Object[,] o)
{
Object[,] result = null;
try
{
Microsoft.Office.Interop.Excel.ApplicationClass excel = new Microsoft.Office.Interop.Excel.ApplicationClass();
result = (System.Object[,])excel.WorksheetFunction.MInverse(o);
Console.WriteLine("逆矩阵为:");
for (int i = 1; i < result.GetLength(0) + 1; i++)
{
for (int j = 1; j < result.GetLength(1) + 1; j++)
{
Console.Write(result[i, j] + "\t");
}
Console.WriteLine(" ");
}
}
catch (Exception e)
{
Console.WriteLine(e);
}
return result;
}
}
}
以上是 C# COMException异常排除 的全部内容, 来源链接: utcz.com/p/189765.html
