C# DataRow.ItemArray 属性

通过一个数组来获取或设置此行的所有值。
命名空间:System.Data

程序集:System.Data（在 system.data.dll 中）

代码示例：

private void CreateRowsWithItemArray()

 // Make a DataTable using the function below.

 DataTable dt = MakeTableWithAutoIncrement();

 DataRow relation;

 // Declare the array variable.

 object [] rowArray = new object[2];

 // Create 10 new rows and add to DataRowCollection.

 for(int i = 0; i i++)

 rowArray[0]=null;

 rowArray[1]= "item " + i;

 relation = dt.NewRow();

 relation.ItemArray = rowArray;

 dt.Rows.Add(relation);

 PrintTable(dt);

private DataTable MakeTableWithAutoIncrement()

 // Make a table with one AutoIncrement column.

 DataTable table = new DataTable("table");

 DataColumn idColumn = new DataColumn("id", 

 Type.GetType("System.Int32"));

 idColumn.AutoIncrement = true;

 idColumn.AutoIncrementSeed = 10;

 table.Columns.Add(idColumn);

 DataColumn firstNameColumn = new DataColumn("Item", 

 Type.GetType("System.String"));

 table.Columns.Add(firstNameColumn);

 return table;

private void PrintTable(DataTable table)

 foreach(DataRow row in table.Rows)

 foreach(DataColumn column in table.Columns)

 Console.WriteLine(row[column]);

}
