ActivityLibrary for Sharepoint Designer

本文关键字：Designer Sharepoint for ActivityLibrary | 更新日期: 2023-09-27 18:07:36

我正在尝试实现一个MSDN教程来创建Sharepoint Designer的活动库，它给了我这个错误:

Namespace1.CreateTaskInListOnSite' does not contain a definition for 'ListName' and no extension method 'ListName' accepting a ...

， AssignedTo和'SiteUrl '相同。

不应该' assigndto '， 'ListName'和'SiteUrl'从SequenceActivity类继承成员?

下面是错误的代码:

protected override ActivityExecutionStatus 
Execute(ActivityExecutionContext executionContext)
{
    try
    {
        SPSite sitecollection = new SPSite(this.SiteUrl); //here
        SPWeb web = sitecollection.OpenWeb();
        SPUser user = web.Users[this.AssignTo[0].ToString()]; // here
        SPList list = web.Lists[this.ListName]; // and here
        SPListItem item = list.Items.Add();
        item["Title"] = this.TaskTitle; 
        item["AssignedTo"] = user; 
        item.Update();
    } 
    catch (Exception ex)
    {
        EventLog.WriteEntry("MSDN Workflow", ex.ToString());
    }
    return ActivityExecutionStatus.Closed; 
}

.actions文件:

<?xml version="1.0" encoding="utf-8" ?>
<WorkflowInfo>
<Actions Sequential="then" Parallel="and">
<Action Name="Create Task in List On Site"

. actions文件将ClassName调用为MSDN.HowTo。CreateTaskInListOnSite，在您的代码文件中，您似乎使用命名空间Namespace1。两者必须匹配。

所以要么你把。actions改成这个:

<Action Name="Create Task in List On Site"
 ClassName="MSDN.HowTo.CreateTaskInListOnSite" .... />

或者将代码文件中的名称空间定义更改为MSDN.HowTo.

程序集属性值也必须正确。可以使用sn.exe工具检索程序集的公钥令牌。
