//读取EXCEL的方法 (用范围区域读取数据)

missing, missing, missing, true, missing, missing, missing, missing, missing);
//取得第一个工作薄
Worksheet ws = (Worksheet)wb.Worksheets.get_Item(1);
//取得总记录行数 (包括标题列)
int rowsint = ws.UsedRange.Cells.Rows.Count; //得到行数
//int columnsint = mySheet.UsedRange.Cells.Columns.Count;//得到列数
//取得数据范围区域 (不包括标题列)

//将新值赋给一个数组
string[,] arry = new string[rowsint-1, 2];
