窗体程序中二维数组展示到DataGridView

 

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;        }
