DataTable添加列和行的三种方法

DataTable添加列和行的三种方法

#region 方法一:

DataTable tblDatas = new DataTable("Datas");

DataColumn dc = null;

dc = tblDatas.Columns.Add("ID", Type.GetType("System.Int32"));

dc.AutoIncrement = true;//自动增加

dc.AutoIncrementSeed = 1;//起始为1

dc.AutoIncrementStep = 1;//步长为1

dc.AllowDBNull = false;

dc = tblDatas.Columns.Add("Product", Type.GetType("System.String"));

dc = tblDatas.Columns.Add("Version", Type.GetType("System.String"));

dc = tblDatas.Columns.Add("Description", Type.GetType("System.String"));

DataRow newRow;

newRow = tblDatas.NewRow();

newRow["Product"] = "大话西游";

newRow["Version"] = "2.0";

newRow["Description"] = "我很喜欢";

tblDatas.Rows.Add(newRow);

newRow = tblDatas.NewRow();

newRow["Product"] = "梦幻西游";

newRow["Version"] = "3.0";

newRow["Description"] = "比大话更幼稚";

tblDatas.Rows.Add(newRow);

#endregion

#region 方法二:

DataTable tblDatas = new DataTable("Datas");

tblDatas.Columns.Add("ID", Type.GetType("System.Int32"));

tblDatas.Columns[0].AutoIncrement = true;

tblDatas.Columns[0].AutoIncrementSeed = 1;

tblDatas.Columns[0].AutoIncrementStep = 1;

tblDatas.Columns.Add("Product", Type.GetType("System.String"));

tblDatas.Columns.Add("Version", Type.GetType("System.String"));

tblDatas.Columns.Add("Description", Type.GetType("System.String"));
