ParallelForEach<T>.Values 属性

定义

命名空间:

System.Activities.Statements

程序集:

System.Activities.dll

值的集合，用作 Body 中所包含活动的每个迭代的参数。

public:
 property System::Activities::InArgument<System::Collections::Generic::IEnumerable<T> ^> ^ Values { System::Activities::InArgument<System::Collections::Generic::IEnumerable<T> ^> ^ get(); void set(System::Activities::InArgument<System::Collections::Generic::IEnumerable<T> ^> ^ value); };

[System.Activities.RequiredArgument]
public System.Activities.InArgument<System.Collections.Generic.IEnumerable<T>> Values { get; set; }

[<System.Activities.RequiredArgument>]
member this.Values : System.Activities.InArgument<seq<'T>> with get, set

Public Property Values As InArgument(Of IEnumerable(Of T))

属性值

InArgument<IEnumerable<T>>

值的集合。

属性

RequiredArgumentAttribute

示例

下面的代码示例演示如何设置 ParallelForEach<T> 活动的 Values 属性。 此示例摘自 公司购买过程 示例。

// invite all vendors and wait for their proposals
new ParallelForEach<Vendor>
{
    DisplayName = "Get vendor proposals",
    Values = new InArgument<IEnumerable<Vendor>>(ctx =>this.Rfp.Get(ctx).InvitedVendors),
    Body = new ActivityAction<Vendor>()
    {
        Argument = iterationVariableVendor,
        Handler = new Sequence
        {
            Variables = { tmpValue },
            Activities =
            {
                // waits for a vendor proposal (creates a bookmark for a vendor)
                new WaitForVendorProposal
                {
                    VendorId = new LambdaValue<int>(ctx =>iterationVariableVendor.Get(ctx).Id) ,
                    Result = new OutArgument<double>(tmpValue)
                },

                // after the vendor proposal is received, it is registered in the Request for Proposals
                new InvokeMethod
                {
                    TargetObject = new InArgument<RequestForProposal>(ctx =>this.Rfp.Get(ctx)),
                    MethodName = "RegisterProposal",
                    Parameters =
                    {
                        new InArgument<Vendor>(iterationVariableVendor),
                        new InArgument<double>(tmpValue)
                    }
                },
            }
        }
    }
},
