AsaParameter class
The value of the parameter.
object Value
Read-write
IDataParameter.Value
For input parameters, the value is bound to the AsaCommand that is sent to the server. For output and return value parameters, the value is set on completion of the AsaCommand and after the AsaDataReader is closed.
When sending a null parameter value to the server, the user must specify DBNull, not null. The null value in the system is an empty object that has no value. DBNull is used to represent null values.
If the application specifies the database type, the bound value is converted to that type when the provider sends the data to the server. The provider attempts to convert any type of value if it supports the IConvertible interface. Conversion errors may result if the specified type is not compatible with the value.
Both the DbType and AsaDbType properties can be inferred by setting the Value.
The Value property is overwritten by Update.
