DataTableReader.GetInt32 Method

Gets the value of the specified column as a 32-bit signed integer.

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

public override int GetInt32(
	int ordinal
)

Parameters

ordinal
Type: System.Int32

The zero-based column ordinal

Return Value

Type: System.Int32
The value of the specified column.

Implements

IDataRecord.GetInt32(Int32)

ExceptionCondition
ArgumentOutOfRangeException

The index passed was outside the range of 0 to FieldCount - 1.

DeletedRowInaccessibleException

An attempt was made to retrieve data from a deleted row.

InvalidOperationException

An attempt was made to read or access a column in a closed DataTableReader .

InvalidCastException

The specified column does not contain a 32-bit signed integer value.

No conversions are performed; therefore, the data retrieved must already be an Int32 or coercible to an Int32.

Call IsDBNull to see if there are null values before calling this method.

The following example displays the contents of the column numbered 2 within the passed-in DataTableReader. If the value the column within a particular row is null, the code displays the text <NULL>. If the data within the column is not of the correct type, the example displays an error message for each row.

private static void PrintColumn(DataTableReader reader)
{
    // Loop through all the rows in the DataTableReader 
    while (reader.Read())
    {
        if (reader.IsDBNull(2))
        {
            Console.Write("<NULL>");
        }
        else
        {
            try
            {
                Console.Write(reader.GetInt32(2));
            }
            catch (InvalidCastException)
            {
                Console.Write("Invalid data type.");
            }
        }
        Console.WriteLine();
    }
}
