Constructors
AdoDotNetParameter(DbParameter, Boolean) |
Initializes a new instance of the AdoDotNetParameter class with a parameter object and an indication of whether the parameter is derived using the DeriveParameters(String, DataCommandType, Int32) method. |
AdoDotNetParameter(DbParameter) |
Initializes a new instance of the AdoDotNetParameter class with a parameter object. |
AdoDotNetParameter(String, Boolean) |
Initializes a new instance of the AdoDotNetParameter class with the name of the data provider and an indication of whether the parameter is derived using the DeriveParameters(String, DataCommandType, Int32) method. |
AdoDotNetParameter(String) |
Initializes a new instance of the AdoDotNetParameter class with a parameter string value. |
Fields
NullSize |
A public size constant holding the value of zero. (Inherited from DataParameter) |
Properties
DefaultSize |
Gets an integer value specifying the default size for the current parameter type. (Inherited from DataParameter) |
Descriptor |
Gets information that describes the data parameter. (Inherited from DataParameter) |
Direction |
Gets or sets a DataParameterDirection object specifying the direction of the parameter. (Inherited from DataParameter) |
HasDescriptor |
Gets a value indicating whether the data parameter exposes its IVsDataParameterDescriptor implementation through the Descriptor property. |
IsDerived |
Gets a Boolean value that indicates whether the current parameter was derived from the data source. (Inherited from DataParameter) |
IsFixedSize |
Gets a value indicating whether the size for the current parameter type is fixed. |
IsNullable |
Gets a Boolean value indicating whether the current parameter can have a null value provided that it is derived. (Inherited from DataParameter) |
IsOptional |
Gets a Boolean value indicating whether the current parameter is optional, provided that it is derived. (Inherited from DataParameter) |
Name |
Gets or sets the string literal name of the current parameter. (Inherited from DataParameter) |
Parameter |
Gets the DbParameter object representing the command parameter. |
Size |
Gets or sets an integer value specifying the size of the parameter. (Inherited from DataParameter) |
Type |
Gets or sets the data source–specific type of the parameter. (Inherited from DataParameter) |
Value |
Gets or sets the value of the parameter. (Inherited from DataParameter) |
Methods
GetDirectionCore() |
Retrieves the parameter direction. |
GetIsNullableCore() |
Retrieves a Boolean value indicating whether this parameter can be null. |
GetIsOptionalCore() |
Retrieves a Boolean value indicating whether the parameter is optional. (Inherited from DataParameter) |
GetNameCore() |
Retrieves the name of the parameter. |
GetSizeCore() |
Retrieves an integer value specifying the size of the parameter. |
GetTypeCore() |
Retrieves the data source–specific type of the parameter. |
GetTypeFrom(Object) |
Maps the value type to a DbType value and returns the string equivalent. |
GetValueCore() |
Retrieves the value of a specified parameter. |
IsSupportedDirection(DataParameterDirection) |
Retrieves a Boolean value indicating whether the specified parameter direction is supported. (Inherited from DataParameter) |
IsValidType(String) |
Retrieves a Boolean value indicating whether the specified data source–specific type is a valid type. |
OnDirectionChanged() |
Called when the Direction property is changed to signal a change in the parameter direction. (Inherited from DataParameter) |
OnDirectionChanging(DataParameterDirection) |
Called when the Direction property is about to change. (Inherited from DataParameter) |
OnNameChanged() |
Called when the Name property has changed. (Inherited from DataParameter) |
OnNameChanging(String) |
Called when the Name property is about to change. (Inherited from DataParameter) |
OnSizeChanged() |
Called when the Size property has changed. (Inherited from DataParameter) |
OnSizeChanging(Int32) |
Called when the Size property is about to change. (Inherited from DataParameter) |
OnTypeChanged() |
Called when the Type property has changed. (Inherited from DataParameter) |
OnTypeChanging(String) |
Called when the Type property is about to change. (Inherited from DataParameter) |
OnValueChanged() |
Called when the Value property has changed. (Inherited from DataParameter) |
OnValueChanging(Object) |
Called when the Value property is about to change. (Inherited from DataParameter) |
Parse(String) |
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). |
SetDirectionCore(DataParameterDirection) |
Sets the direction of the parameter by using the DataParameterDirection enumeration. |
SetNameCore(String) |
Sets the name of the parameter. |
SetSizeCore(Int32) |
Sets an integer value specifying the size of this parameter. |
SetTypeCore(String) |
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. |
SetValueCore(Object) |
Sets the value of the parameter. |
ToString() |
Retrieves a string representation of the value of the current parameter. (Inherited from DataParameter) |
TryConvertValue(Object, String) |
Attempts to convert the specified value to the specified type. (Inherited from DataParameter) |
