方法一:

DataTable tblDatas = new DataTable(\"Datas\");

DataColumn dc = null;

dc = tblDatas.Columns.Add(\"ID\

dc.AutoIncrement = true;//自動增加

dc.AutoIncrementSeed = 1;//起始為1

dc.AutoIncrementStep = 1;//步長為1

dc.AllowDBNull = false;//

dc = tblDatas.Columns.Add(\"Product\

dc = tblDatas.Columns.Add(\"Version\

dc = tblDatas.Columns.Add(\"Description\

DataRow newRow;

newRow = tblDatas.NewRow();

newRow[\"Product\"] = \"水果刀\";

newRow[\"Version\"] = \"2.0\";

newRow[\"Description\"] = \"打架專用\";

tblDatas.Rows.Add(newRow);

newRow = tblDatas.NewRow();

newRow[\"Product\"] = \"折疊凳\";

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\

tblDatas.Columns[0].AutoIncrement = true;

tblDatas.Columns[0].AutoIncrementSeed = 1;

tblDatas.Columns[0].AutoIncrementStep = 1;

tblDatas.Columns.Add(\"Product\

tblDatas.Columns.Add(\"Version\

tblDatas.Columns.Add(\"Description\

tblDatas.Rows.Add(new object[]{null,\"a\

tblDatas.Rows.Add(new object[] { null, \"a\

tblDatas.Rows.Add(new object[] { null, \"a\

tblDatas.Rows.Add(new object[] { null, \"a\

tblDatas.Rows.Add(new object[] { null, \"a\

方法一:

DataTable tblDatas = newDataTable(\"Datas\");

DataColumn dc = null;

//賦值給dc，是便于對每一個datacolumn的操作

dc =tblDatas.Columns.Add(\"ID\

dc.AutoIncrement= true;//自動增加

dc.AutoIncrementSeed = 1;//起始為1

dc.AutoIncrementStep = 1;//步長為1

dc.AllowDBNull = false;//

dc = tblDatas.Columns.Add(\"Product\

dc = tblDatas.Columns.Add(\"Version\

dc = tblDatas.Columns.Add(\"Description\

DataRow newRow;

newRow = tblDatas.NewRow();

newRow[\"Product\"] = \"大話西游\";

newRow[\"Version\"] = \"2.0\";

newRow[\"Description\"] = \"我很喜歡\";

tblDatas.Rows.Add(newRow);

newRow = tblDatas.NewRow();

newRow[\"Product\"] = \"夢幻西游\";

newRow[\"Version\"] = \"3.0\";

newRow[\"Description\"] = \"比大話更幼稚\";

tblDatas.Rows.Add(newRow);

方法二:

DataTable tblDatas = newDataTable(\"Datas\");

tblDatas.Columns.Add(\"ID\

tblDatas.Columns[0].AutoIncrement = true;

tblDatas.Columns[0].AutoIncrementSeed = 1;

tblDatas.Columns[0].AutoIncrementStep = 1;

tblDatas.Columns.Add(\"Product\

tblDatas.Columns.Add(\"Version\

tblDatas.Columns.Add(\"Description\

tblDatas.Rows.Add(newobject[]{null,\"ablDatas.Rows.Add(newobject[] { null, \"a\

tblDatas.Rows.Add(new object[] { null, \"a\

tblDatas.Rows.Add(new object[] { null, \"a\

tblDatas.Rows.Add(new object[] { null, \"a\

方法三：

DataTable table = new DataTable ();

//創(chuàng)建table的第一列

DataColumn priceColumn = new DataColumn();

//該列的數(shù)據(jù)類型

priceColumn.DataType = System.Type.GetType(\"System.Decimal\");

//該列得名稱

priceColumn.ColumnName = \"price\";

//該列得默認(rèn)值

priceColumn.DefaultValue =50;

// 創(chuàng)建table的第二列

DataColumn taxColumn = new DataColumn();

taxColumn.DataType = System.Type.GetType(\"System.Decimal\");

//列名

taxColumn.ColumnName = \"tax\";

//設(shè)置該列得表達(dá)式，用于計算列中的值或創(chuàng)建聚合列

taxColumn.expression_r_r = \"price *0.0862\";

// Create third column.

DataColumn totalColumn = new DataColumn();

totalColumn.DataType = System.Type.GetType(\"System.Decimal\");

totalColumn.ColumnName = \"total\";

//該列的表達(dá)式，值是得到的是第一列和第二列值得和

totalColumn.expression_r_r = \"price + tax\";

// 將所有的列添加到table上

table.Columns.Add(priceColumn);

table.Columns.Add(taxColumn);

table.Columns.Add(totalColumn);

//創(chuàng)建一行

DataRow row = table.NewRow();

//將此行添加到table中

table.Rows.Add(row);

//將table放在試圖中

DataViewview = new DataView(table);

dg.DataSource = view;

dg.DataBind();
