<remarks>
|
||
|
|
The number of the parameters in the collection must be equal to the number of
|
||
|
|
parameter placeholders within the command text, or an exception will be generated.

<example>
|
||
|
|
The following example creates multiple instances of <see cref="MySqlParameter"/>
|
||
|
|
through the <B>MySqlParameterCollection</B> collection within the <see cref="MySqlDataAdapter"/>.
|
||
|
|
These parameters are used to select data within the data source and place the data in
|
||
|
|
the <see cref="System.Data.DataSet"/>. This code assumes that a <B>DataSet</B> and a <B>MySqlDataAdapter</B>
|
||
|
|
have already been created with the appropriate schema, commands, and connection.
