Sets this DataValue instance equal to another DataValue instance.

Creates a copy of this instance.

Creates a DataValue instance of a given data type.

Creates a DataValue instance of a given data type and with a provided error value.

Creates a DataValue instance of a given data type and with a provided initial value.

Creates a DataValue instance of a given runtime type.

Creates a DataValue instance of a given runtime type and with a provided initial value.

Creates a DataValue instance of a given runtime type and with a provided initial value. This method is redundant but useful in practice.

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

Gets the Type of the current instance.

Creates a shallow copy of the current Object.

Makes this DataValue instance represent a null value. That is, an invalid value with a null data error. After the method call, HasValidValue will return false, IsNullValue will return true, and HasDataError will return false. The ValidValue property will be null or default(T).

Gets or sets the data error contained in this DataValue instance. The getter returns null if HasDataError is false. After invoking the setter HasDataError will be true, HasValidValue and IsNullValue will be false, and ValidValue will return a default value.

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.

Gets or sets the data error associated with this DataValue.

Gets a value indicating whether this DataValue (i) is invalid and (ii) has an associated data error. If HasDataError is true, then HasValidValue and IsNullValue are both false.

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.

Gets the row index associated with this DataValue, if applicable.

Gets a value indicating whether the DataValue represents an error.

Gets a value indicating whether this DataValue instance represents a null value, or, more precisely, an invalid value with a null data error.

Gets or sets a value indicating whether the contained data value is valid.

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.

Gets the value contained in this DataValue instance.
