二维数组展示到DataGridView(c#)

        public void TwoDArrayShowINDatagridview(string[,] arr)
        {
            DataTable dt = new DataTable();
            for (int column = 0; column < arr.GetLength(1); column++)
                dt.Columns.Add(arr[0, column], typeof(string)); //新增列；列名显示二维数组的第一个元素-标题

            for (int row = 1; row < arr.GetLength(0); row++) //填充行数据
            {
                DataRow dr = dt.NewRow();
                for (int column = 0; column < arr.GetLength(1); column++)
                    dr[column] = arr[row, column];
                dt.Rows.Add(dr);
            }

            this.dataGridView.DataSource = dt;
        }
