C#dataGridView添加自增列

//創建一個列
DataColumn column = new DataColumn();
//列名
//column.ColumnName = "已掃描";
//是否自增
column.AutoIncrement = true;
//自增從哪一行開始
column.AutoIncrementSeed = 1;
//自增量
column.AutoIncrementStep = 1;

 

//創建一個表存放column
DataTable columntable = new DataTable();
//將新增的自增列加入table
columntable.Columns.Add(column);

 

//查詢數據 QueryData()為查詢數據庫返回DataTable的方法
//DataTable dataTable = QueryData();

////將查詢到的數據跟創建的自增列合並
columntable.Merge(dataTable);

//將數據顯示到dataGridView

dataGridView.DataSource = columntable;
