DataColumnCollection.Item Property (String)

Gets the DataColumn from the collection with the specified name.

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

public DataColumn this [
	string name
] { get; 
/** @property */
public DataColumn get_Item (String name)

JScript supports the use of indexed properties, but not the declaration of new ones.

Parameters

name

The ColumnName of the column to return.

Property Value

The DataColumn in the collection with the specified ColumnName; otherwise a null value if the DataColumn does not exist.

Item is conditionally case-sensitive when it searches for column names. For example, if one DataColumn is named "mydatacolumn" and another is named "Mydatacolumn", a string used to search for one of the columns is regarded as case-sensitive. However, if "mydatacolumn" exists and "Mydatacolumn" does not, the search string is regarded as case-insensitive.

The following example uses the Item property to print the DataType value of a DataColumn object specified by index.

private void PrintDataType(DataTable table)
{
    // Get the DataColumnCollection from a DataTable in a DataSet.
    DataColumnCollection columns = table.Columns;

    // Print the column's data type.
    Console.WriteLine(columns["id"].DataType);
