The DataValue type exposes the following members.
Properties
| Name | Description | |
|---|---|---|
 | DataType |
Gets the data type corresponding to the runtime values that can be stored in this value container.
The data type is fixed, since a data value cannot be used for values of varying types.
|
| ErrorValue | Obsolete.
Gets or sets the data error associated with this DataValue.
|
| HasValidValue |
Gets a value indicating whether this DataValue contains a valid value.
If HasValidValue is false, then either IsNullValue is true or HasDataError is true, but not both.
If HasValidValue is true, the IsNullValue and HasDataError are both false.
|
| Index | Obsolete.
Gets the row index associated with this DataValue, if applicable.
|
| IsError | Obsolete.
Gets a value indicating whether the DataValue represents an error.
|
| IsNullValue |
Gets a value indicating whether this DataValue instance represents a null value,
or, more precisely, an invalid value with a null data error.
|
| IsValid | Obsolete.
Gets or sets a value indicating whether the contained data value is valid.
|
| ValidValue |
Gets or sets the runtime value contained in this DataValue instance, as a boxed value.
The getter returns null for reference types and default(T) for value types, if the HasValidValue is false.
After setting a valid value HasValidValue will be true, HasDataError and IsNullValue will be false,
and DataError will return null.
|
| Value | Obsolete.
Gets the value contained in this DataValue instance.
