## Remarks
 Derived expression types might perform stricter type checks when the <xref:System.Data.Common.CommandTrees.DbUnaryExpression.Argument> property is set. For example, <xref:System.Data.Common.CommandTrees.DbDistinctExpression> requires that its argument expression has a collection result type. Typically, derived expression types will not allow <xref:System.Data.Common.CommandTrees.DbUnaryExpression.Argument*> to be set to an expression with a result type that is not equal or promotable to the result type of the current value.

        <exception cref="T:System.ArgumentException">The expression is not associated with the command tree of a <see cref="T:System.Data.Common.CommandTrees.DbUnaryExpression" />, or its result type is not equal or promotable to the required type for the argument.</exception>
