System.Data.SqlClient Namespace SqlParameterCollection Class
Returns the location of a parameter within the collection.
1. Returns the location of a given SqlParameter within the collection.
2. Returns the location of the SqlParameter with the given name within the collection.
The following example first uses the Contains property to find an SqlParameter with a given ParameterName within the Parameters collection of a specifed SqlCommand object. If the parameter exists, the example uses the IndexOf method to display the index of the parameter; otherwise, the example displays an error.
NOTE: This example uses one of the overloaded versions of the IndexOf method. For other examples that may be available, see the individual overload topics.
public void SearchSqlParams ( SqlCommand myCmd ) {
SqlParameterCollection myParams = myCmd.Parameters;
if ( myParams.Contains ( "@Model" ) )
MessageBox.Show ( "Name: " + myParams [ "@Model" ].ToString ( ) +
"Index: " + myParams.IndexOf ( "@Model" ).ToString ( ) );
else
MessageBox.Show ( "Sorry, no such parameter found in the collection" );
}
Public Sub SearchSqlParams ( ByVal myCmd As SqlCommand )
Dim myParams As SqlParameterCollection = myCmd.Parameters
If myParams.Contains ( "@Model" ) Then
MessageBox.Show ( "Name: " & myParams ( "@Model" ).ToString ( ) & _
"Index: " & myParams.IndexOf ( "@Model" ).ToString ( ) )
Else
MessageBox.Show ( "Sorry, no such parameter found in the collection" )
End If
