二維數組轉換成爲DataTable

ConvertToDataTable方法就是轉化方法，參數爲一個二維數組

public static DataTable ConvertToDataTable(string[,] arr)
    {

        DataTable dataSouce = new DataTable();
        for (int i = 0; i < arr.GetLength(1); i++)
        {
            DataColumn newColumn = new DataColumn(GetCode(i), arr[0, 0].GetType());
            dataSouce.Columns.Add(newColumn);
        }
        for (int i = 0; i < arr.GetLength(0); i++)
        {
            DataRow newRow = dataSouce.NewRow();
            for (int j = 0; j < arr.GetLength(1); j++)
            {
                newRow[GetCode(j)] = arr[i, j];
            }
            dataSouce.Rows.Add(newRow);
        }
        return dataSouce;

    }

接着綁定到GridView中去

DataTable newdt = ConvertToDataTable(myArea);

        this.grid.DataSource = newdt;
        this.grid.DataBind();
