Methods

 

Name

Description

Equals

Determines whether the specified Object is equal to the current Object. (Inherited from Object.)

Finalize

Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)

GetDirectionImpl

Retrieves the parameter direction. (Overrides DataParameter.GetDirectionImpl().)

GetHashCode

Serves as a hash function for a particular type. (Inherited from Object.)

GetIsNullableImpl

Retrieves a Boolean value indicating whether this parameter can be nulla null reference (Nothing in Visual Basic). (Overrides DataParameter.GetIsNullableImpl().)

GetIsOptionalImpl

Retrieves a Boolean value indicating whether this parameter is optional. (Inherited from DataParameter.)

GetNameImpl

Retrieves the name of the parameter. (Overrides DataParameter.GetNameImpl().)

GetPrecisionImpl

Retrieves a byte value specifying the precision of the parameter. (Overrides DataParameter.GetPrecisionImpl().)

GetScaleImpl

Retrieves a byte value specifying the scale of the parameter. (Overrides DataParameter.GetScaleImpl().)

GetSizeImpl

Retrieves an integer value specifying the size of the parameter. (Overrides DataParameter.GetSizeImpl().)

GetType

Gets the type of the current instance. (Inherited from Object.)

GetTypeFrom

Returns a AnsiString for a nulla null reference (Nothing in Visual Basic) or DBNull value; alternatively maps the value type to a DbType value and returns the string equivalent. (Overrides DataParameter.GetTypeFrom(Object).)

GetTypeImpl

Retrieves the data-source-specific type of the parameter. (Overrides DataParameter.GetTypeImpl().)

GetValueImpl

Retrieves the value of a specified parameter. (Overrides DataParameter.GetValueImpl().)

IsSupportedDirection

Retrieves a Boolean value indicating whether the specified parameter direction is supported. (Inherited from DataParameter.)

IsValidType

Retrieves a Boolean value indicating whether the specified data-source-specific type is a valid type. (Overrides DataParameter.IsValidType(String).)

MemberwiseClone

Creates a shallow copy of the current Object. (Inherited from Object.)

OnDirectionChanged

Called when the Direction property is changed to signal a change in the parameter direction. (Inherited from DataParameter.)

OnDirectionChanging

Called when the Direction property is about to change. (Inherited from DataParameter.)

OnNameChanged

Called when the Name property has changed. (Inherited from DataParameter.)

OnNameChanging

Called when the Name property is about to change. (Inherited from DataParameter.)

OnPrecisionChanged

Called when the Precision property has changed. (Inherited from DataParameter.)

OnPrecisionChanging

Called when the Precision property is about to change. (Inherited from DataParameter.)

OnScaleChanged

Called when the Scale property has changed. (Inherited from DataParameter.)

OnScaleChanging

Called when the Scale property is about to change. (Inherited from DataParameter.)

OnSizeChanged

Called when the Size property has changed. (Inherited from DataParameter.)

OnSizeChanging

Called when the Size property is about to change. (Inherited from DataParameter.)

OnTypeChanged

Called when the Type property has changed. (Inherited from DataParameter.)

OnTypeChanging

Called when the Type property is about to change. (Inherited from DataParameter.)

OnValueChanged

Called when the Value property has changed. (Inherited from DataParameter.)

OnValueChanging

Called when the Value property is about to change. (Inherited from DataParameter.)

Parse

Gets the DbType and attempts to parts the input string value into the correct type using primitive type conversions (like Byte.Parse and Int32.Parse). (Overrides DataParameter.Parse(String).)

SetDirectionImpl

Sets the direction of the parameter using the DataParameterDirection enumeration. (Overrides DataParameter.SetDirectionImpl(DataParameterDirection).)

SetNameImpl

Sets the name of the parameter. (Overrides DataParameter.SetNameImpl(String).)

SetPrecisionImpl

Sets a byte value specifying the precision of the parameter. (Overrides DataParameter.SetPrecisionImpl(Byte).)

SetScaleImpl

Sets a byte value specifying the scale of the parameter. (Overrides DataParameter.SetScaleImpl(Byte).)

SetSizeImpl

Sets an integer value specifying the size of this parameter. (Overrides DataParameter.SetSizeImpl(Int32).)

SetTypeImpl

Attempts to parse the string type into a DbType enumeration value using Enum.Parse and if this fails it assumes DbType.Object as the correct DbType. (Overrides DataParameter.SetTypeImpl(String).)

SetValueImpl

Sets the value of this parameter. (Overrides DataParameter.SetValueImpl(Object).)

ToString

Retrieves a string representation of the value of this parameter. (Inherited from DataParameter.)

TryConvertValue

Attempts to convert the specified value to the specified type. (Inherited from DataParameter.)
