DataTableCollection.Contains Method (String, String)

 

Gets a value that indicates whether a DataTable object with the specified name and table namespace exists in the collection.

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

member Contains : 
        name:string *
        tableNamespace:string -> bool

Parameters

name
Type: System.String

The name of the DataTable to find.

tableNamespace
Type: System.String

The name of the DataTable namespace to look in.

Return Value

Type: System.Boolean

true if the specified table exists; otherwise false.

You specify the name of the DataTable object by using the TableName property. If you add a DataTable to the collection with the Add method, passing no arguments, the table is given a default name, based on the order in which the table was added ("Table1", "Table2", and so on).

System_CAPS_noteNote

Returns false when two or more tables have the same name but different namespaces. The call does not succeed if there is any ambiguity when matching a table name to exactly one table.

To get the index of a DataTable, use the IndexOf method.

The following example tests whether a table with the name "Suppliers" exists in the DataTableCollection.
