Methods

Description
Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
.gif "Protected method")
Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
Retrieves the parameter direction. (Overrides DataParameter.GetDirectionCore().)
Serves as a hash function for a particular type. (Inherited from Object.)
Retrieves a Boolean value indicating whether this parameter can be nulla null reference (Nothing in Visual Basic). (Overrides DataParameter.GetIsNullableCore().)
Retrieves a Boolean value indicating whether the parameter is optional. (Inherited from DataParameter.)
Retrieves the name of the parameter. (Overrides DataParameter.GetNameCore().)
Retrieves an integer value specifying the size of the parameter. (Overrides DataParameter.GetSizeCore().)
Gets the type of the current instance. (Inherited from Object.)
Retrieves the data source–specific type of the parameter. (Overrides DataParameter.GetTypeCore().)
Maps the value type to a DbType value and returns the string equivalent. (Overrides DataParameter.GetTypeFrom(Object).)
Retrieves the value of a specified parameter. (Overrides DataParameter.GetValueCore().)
Retrieves a Boolean value indicating whether the specified parameter direction is supported. (Inherited from DataParameter.)
Retrieves a Boolean value indicating whether the specified data source–specific type is a valid type. (Overrides DataParameter.IsValidType(String).)
Creates a shallow copy of the current Object. (Inherited from Object.)
Called when the Direction property is changed to signal a change in the parameter direction. (Inherited from DataParameter.)
Called when the Direction property is about to change. (Inherited from DataParameter.)
Called when the Name property has changed. (Inherited from DataParameter.)
Called when the Name property is about to change. (Inherited from DataParameter.)
Called when the Size property has changed. (Inherited from DataParameter.)
Called when the Size property is about to change. (Inherited from DataParameter.)
Called when the Type property has changed. (Inherited from DataParameter.)
Called when the Type property is about to change. (Inherited from DataParameter.)
Called when the Value property has changed. (Inherited from DataParameter.)
Called when the Value property is about to change. (Inherited from DataParameter.)
Gets the DbType and attempts to parse the input string value into the correct type by using primitive type conversions (like Byte.Parse and Int32.Parse). (Overrides DataParameter.Parse(String).)
Sets the direction of the parameter by using the DataParameterDirection enumeration. (Overrides DataParameter.SetDirectionCore(DataParameterDirection).)
Sets the name of the parameter. (Overrides DataParameter.SetNameCore(String).)
Sets an integer value specifying the size of this parameter. (Overrides DataParameter.SetSizeCore(Int32).)
Attempts to parse the string type into a DbType enumeration value by using Enum.Parse. If this fails, the method assumes DbType.Object as the correct DbType. (Overrides DataParameter.SetTypeCore(String).)
Sets the value of the parameter. (Overrides DataParameter.SetValueCore(Object).)
Retrieves a string representation of the value of the current parameter. (Inherited from DataParameter.)
Attempts to convert the specified value to the specified type. (Inherited from DataParameter.)

Description

Gets an integer value specifying the default size for the current parameter type. (Inherited from DataParameter.)
.gif "Public property")
Gets information that describes the data parameter. (Inherited from DataParameter.)
Gets or sets a DataParameterDirection object specifying the direction of the parameter. (Inherited from DataParameter.)
Gets a value indicating whether the data parameter exposes its IVsDataParameterDescriptor implementation through the Descriptor property. (Overrides DataParameter.HasDescriptor.)
Gets a Boolean value that indicates whether the current parameter was derived from the data source. (Inherited from DataParameter.)
Gets a value indicating whether the size for the current parameter type is fixed. (Overrides DataParameter.IsFixedSize.)
Gets a Boolean value indicating whether the current parameter can have a null value provided that it is derived. (Inherited from DataParameter.)
Gets a Boolean value indicating whether the current parameter is optional, provided that it is derived. (Inherited from DataParameter.)
Gets or sets the string literal name of the current parameter. (Inherited from DataParameter.)
Gets the DbParameter object representing the command parameter.
Gets or sets an integer value specifying the size of the parameter. (Inherited from DataParameter.)
Gets or sets the data source–specific type of the parameter. (Inherited from DataParameter.)
Gets or sets the value of the parameter. (Inherited from DataParameter.)
