Adds an OdbcParameter to the OdbcParameterCollection given the parameter name and value.

public:
 System::Data::Odbc::OdbcParameter ^ Add(System::String ^ parameterName, System::Object ^ value);

[System.Obsolete("Add(String parameterName, Object value) has been deprecated. Use AddWithValue(String parameterName, Object value) instead.")]

public System.Data.Odbc.OdbcParameter Add (string parameterName, object value);

[<System.Obsolete("Add(String parameterName, Object value) has been deprecated. Use AddWithValue(String parameterName, Object value) instead.")>]
override this.Add : string * obj -> System.Data.Odbc.OdbcParameter

member this.Add : string * obj -> System.Data.Odbc.OdbcParameter

[<System.Obsolete("Add(String parameterName, Object value) has been deprecated.  Use AddWithValue(String parameterName, Object value).  http://go.microsoft.com/fwlink/?linkid=14202", false)>]
override this.Add : string * obj -> System.Data.Odbc.OdbcParameter

Public Function Add (parameterName As String, value As Object) As OdbcParameter

Parameters

parameterName: String

The name of the parameter.

value: Object

The Value of the OdbcParameter to add to the collection.

Returns

OdbcParameter

The index of the new OdbcParameter object.

Attributes: ObsoleteAttribute

Exceptions

InvalidCastException

The value parameter is not an OdbcParameter.

Remarks

Use caution when using this overload of the Add method to specify integer parameter values. Because this overload takes a value of type Object, you must convert the integer value to an Object type when the value is zero, as the following C# example demonstrates.

parameters.Add("@pname", Convert.ToInt32(0));

If you do not perform this conversion, the compiler will assume you are attempting to call the OdbcParameterCollection.Add overload.
