Assembly:  System.Data (in System.Data.dll)

public Object[] ItemArray { get; set; }

Property Value

Type: System.Object[]

A value in the array does not match its DataType in its respective DataColumn.

You can use this property to set or get values for this row through an array. If you use this property to set values, the array must have the same size and ordering as the column collection. Passing null in the ItemArray indicates that no value was specified.

Users can generate exceptions in the ColumnChanging event or the RowChanging event.

The following examples show how to get and set values using the ItemArray property.

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 <10; i++)
        rowArray[1]= "item " + i;
        relation = dt.NewRow();
        relation.ItemArray = rowArray;

private DataTable MakeTableWithAutoIncrement()
    // Make a table with one AutoIncrement column.
    DataTable table = new DataTable("table");
    DataColumn idColumn = new DataColumn("id", 
    idColumn.AutoIncrement = true;
    idColumn.AutoIncrementSeed = 10;

    DataColumn firstNameColumn = new DataColumn("Item", 
    return table;

private void PrintTable(DataTable table)
    foreach(DataRow row in table.Rows)
        foreach(DataColumn column in table.Columns)
