Gets or sets the DbExpression that defines the argument.
public:
property System::Data::Common::CommandTrees::DbExpression ^ Argument { System::Data::Common::CommandTrees::DbExpression ^ get(); };public System.Data.Common.CommandTrees.DbExpression Argument { get; }member this.Argument : System.Data.Common.CommandTrees.DbExpressionPublic ReadOnly Property Argument As DbExpressionProperty Value
The DbExpression that defines the argument.
Exceptions
The expression is null.
The expression is not associated with the command tree of a DbUnaryExpression, or its result type is not equal or promotable to the required type for the argument.
Remarks
Derived expression types might perform stricter type checks when the Argument property is set. For example, DbDistinctExpression requires that its argument expression has a collection result type. Typically, derived expression types will not allow 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.
