Remarks

You can use the ProfileParameter class to bind the value of an ASP.NET Profile parameter to a parameter used in a parameterized SQL query, business object method, or filtering expression.

The ProfileParameter class provides the PropertyName property in addition to those inherited from the Parameter class. The PropertyName property identifies the ASP.NET Profile property from which the ProfileParameter retrieves a value.

Note

Controls that bind data to the parameter might throw an exception if a ProfileParameter object is specified but no corresponding profile property is set. Similarly, they might display no data if the profile property is set with null. Set the DefaultValue property to avoid these situations where appropriate.

Constructors

ProfileParameter() ProfileParameter() ProfileParameter() ProfileParameter()

Initializes a new instance of the ProfileParameter class.

ProfileParameter(ProfileParameter) ProfileParameter(ProfileParameter) ProfileParameter(ProfileParameter) ProfileParameter(ProfileParameter)

Initializes a new instance of the ProfileParameter class with the values of the instance specified by the original parameter.

ProfileParameter(String, DbType, String) ProfileParameter(String, DbType, String) ProfileParameter(String, DbType, String) ProfileParameter(String, DbType, String)

Initializes a new instance of the ProfileParameter class, using the specified property name to identify which ASP.NET Profile property to bind to.

ProfileParameter(String, String) ProfileParameter(String, String) ProfileParameter(String, String) ProfileParameter(String, String)

Initializes a new named instance of the ProfileParameter class, using the specified property name to identify which ASP.NET Profile property to bind to.

ProfileParameter(String, TypeCode, String) ProfileParameter(String, TypeCode, String) ProfileParameter(String, TypeCode, String) ProfileParameter(String, TypeCode, String)

Initializes a new named and strongly typed instance of the ProfileParameter class, using the specified property name to identify which ASP.NET Profile property to bind to.
