WF4 AssignActivity - 多行语句中断设计器

发布于 2024-11-28 17:10:05 字数 1294 浏览 4 评论 0原文

我正在使用 WF4 设计器来构建自定义活动。

每当我尝试将多行语句分配给设计器内的分配活动中的“值”属性并重建项目时，设计器都会因以下错误而中断：“XC1020：XAML MSBuild 任务中发生生成错误：''xml: space' 是重复的属性名称。”

例如，以下语句（无换行符）是有效的：

New WorkItem() With {.AssociatedProgrammeId = associatedProgrammeId, .AssociatedQuestionnaireId = associatedQuestionnaireId, .AssociatedQuestionnaireInstanceId = associatedQuestionnaireInstanceId, .DelayUntil = delayUntil}

但此语句破坏了设计器（在构建项目后）：

New WorkItem() With
{
    .AssociatedProgrammeId = associatedProgrammeId,
    .AssociatedQuestionnaireId = associatedQuestionnaireId,
    .AssociatedQuestionnaireInstanceId = associatedQuestionnaireInstanceId,
    .DelayUntil = delayUntil
}

第二个语句生成以下 XAML：

<Assign.Value>
    <InArgument x:TypeArguments="local:WorkItem" xml:space="preserve">[New WorkItem() With
{
    .AssociatedProgrammeId = associatedProgrammeId,
    .AssociatedQuestionnaireId = associatedQuestionnaireId,
    .AssociatedQuestionnaireInstanceId = associatedQuestionnaireInstanceId,
    .DelayUntil = delayUntil
}]</InArgument>

删除 xml:space="preserve" 并重建修复了设计器，以便可以编辑活动，但会删除 InArgument 中的换行符。

我假设我应该能够向该活动的参数添加多重语句。我想我可能会被磨损，这是设计师的限制？

如果没有，有人可以帮我弄清楚如何让 Visual Studio 表现出来吗？

原文

I am using the WF4 designer to build a custom activity.

Whenever I try to assign a multi line statement to the 'Value' property in an Assign activity within the designer and rebuild my project the designer is broken with the error: "XC1020: Build error occurred in the XAML MSBuild task: ''xml:space' is a duplicate attribute name."

For example the following statement (no line breaks) is valid:

New WorkItem() With {.AssociatedProgrammeId = associatedProgrammeId, .AssociatedQuestionnaireId = associatedQuestionnaireId, .AssociatedQuestionnaireInstanceId = associatedQuestionnaireInstanceId, .DelayUntil = delayUntil}

but this statement breaks the designer (after building the project):

New WorkItem() With
{
    .AssociatedProgrammeId = associatedProgrammeId,
    .AssociatedQuestionnaireId = associatedQuestionnaireId,
    .AssociatedQuestionnaireInstanceId = associatedQuestionnaireInstanceId,
    .DelayUntil = delayUntil
}

The 2nd statement produces the following XAML:

<Assign.Value>
    <InArgument x:TypeArguments="local:WorkItem" xml:space="preserve">[New WorkItem() With
{
    .AssociatedProgrammeId = associatedProgrammeId,
    .AssociatedQuestionnaireId = associatedQuestionnaireId,
    .AssociatedQuestionnaireInstanceId = associatedQuestionnaireInstanceId,
    .DelayUntil = delayUntil
}]</InArgument>

Removing xml:space="preserve" and rebuilding fixes the designer so the the Activity can be edited but removes the line breaks from the InArgument.

I am assuming that I should be able to add a multine statement to the argument for the activity. I guess I could be worng and this is a limitation of the designer?

If not could someone please help me figure out how I can make Visual Studio behave?
