方向
属性可以指向四个方向：
- In：最常见。 用于输入参数。
- 输出：用于输出参数，即活动的结果。
- “输入输出”：很少使用，但在接收数据、修改数据并输出数据以供其他活动使用的活动中非常方便。
- “无”：布尔值和枚举等独立类型不需要方向。 创建这些类型的属性时，请使用“无”。
备注：
Note that Out and InOut properties can only accept variables, not literal values, in UiPath Studio. This makes sense since the activity needs something to which the outputted value can be written.
生成的代码
The Argument direction is seen in the declaration of each property. Notice that FirstNumber and SecondNumber are both InArguments while Sum is an OutArgument.
...
#regio Properties
[LocalizedDisplayName(nameof(Resources.Addition_FirstNumber_DisplayName))]
[LocalizedDescription(nameof(Resources.Addition_FirstNumber_Description))]
[LocalizedCategory(nameof(Resources.Input_Category))]
public InArgument<int> FirstNumber { get; set; }
[LocalizedDisplayName(nameof(Resources.Addition_SecondNumber_DisplayName))]
[LocalizedDescription(nameof(Resources.Addition_SecondNumber_Description))]
[LocalizedCategory(nameof(Resources.Input_Category))]
public InArgument<int> SecondNumber { get; set; }
[LocalizedDisplayName(nameof(Resources.Addition_Sum_DisplayName))]
[LocalizedDescription(nameof(Resources.Addition_Sum_Description))]
[LocalizedCategory(nameof(Resources.Output_Category))]
public OutArgument<int> Sum { get; set; }
#endregio
...

#regio Properties
[LocalizedDisplayName(nameof(Resources.Addition_FirstNumber_DisplayName))]
[LocalizedDescription(nameof(Resources.Addition_FirstNumber_Description))]
[LocalizedCategory(nameof(Resources.Input_Category))]
public InArgument<int> FirstNumber { get; set; }
[LocalizedDisplayName(nameof(Resources.Addition_SecondNumber_DisplayName))]
[LocalizedDescription(nameof(Resources.Addition_SecondNumber_Description))]
[LocalizedCategory(nameof(Resources.Input_Category))]
public InArgument<int> SecondNumber { get; set; }
[LocalizedDisplayName(nameof(Resources.Addition_Sum_DisplayName))]
[LocalizedDescription(nameof(Resources.Addition_Sum_Description))]
[LocalizedCategory(nameof(Resources.Output_Category))]
public OutArgument<int> Sum { get; set; }
#endregio

UiPath Studio 中的效果
将鼠标悬停在“属性”窗格中的每个属性上即可查看其方向。
