复制代码 代码如下:
#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
复制代码 代码如下:
#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"));
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" });
#endregion
