SqlParameter.SqlValue Property

Gets or sets the value of the parameter as an SQL type.

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

[BrowsableAttribute(false)]
public Object SqlValue { get; set; }

Property Value

Type: System.Object
An Object that is the value of the parameter, using SQL types. The default value is null.

For input parameters, the value is bound to the SqlCommand that is sent to the server. For output and return value parameters, the value is set on completion of the SqlCommand and after the SqlDataReader is closed.

When you send 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 tries 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 SqlDbType properties can be inferred by setting the Value.

The Value property is overwritten by SqlDataAdapter.UpdateCommand.

Use the Value property to return parameter values as common language runtime (CLR) types.
