DataTable添加行的方法

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"] = "水果刀";
newRow["Version"] = "2.0";
newRow["Description"] = "打架专用";
tblDatas.Rows.Add(newRow);
newRow = tblDatas.NewRow();
newRow["Product"] = "折叠凳";
newRow["Version"] = "3.0";
newRow["Description"] = "行走江湖七武器之一";
tblDatas.Rows.Add(newRow);
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"));
tblDatas.Rows.Add(new
object[]{null,"a","b","c"});
tblDatas.Rows.Add(new object[] { null, "a", "b", "c"
});
tblDatas.Rows.Add(new object[] { null, "a", "b", "c"
});
tblDatas.Rows.Add(new object[] { null, "a", "b", "c"
});
tblDatas.Rows.Add(new object[] { null, "a", "b", "c"
});
