解锁SharePoint工作流任务
本文提供了一种解决SharePoint工作流中任务被锁定的问题的方法。通过更新任务的WorkflowVersion字段为1，可以解除锁定状态，使任务可以继续进行。
How to unlock the locked tasks in Sharepoint Workflow
Sometimes in Sharepoint Workflow, tasks will get locked and you will not be able to proceed further.
These locks are placed to prevent the task being updated simultaneously. The workflow runtime locks tasks by setting a field (WorkflowVersion)and persisting that to the database.
if workflowversion is 1 then the tasks are "not locked". Any value apart from "1" symbolises that these tasks are "locked".
Ideally to remove the locks, we need to update WorkflowVersion of the task to "1".
Here you go, the sample for it.
Happy Coding :)

public static void UnlockWorkflowTasks(string siteUrl, string webUrl, string listName)
{
using (SPSite site = new SPSite(siteUrl))
{
using (SPWeb web = site.OpenWeb(webUrl))
{
SPList list = web.Lists[listName];
SPListItemCollection items = list.Items;
foreach (SPListItem item in items)
{
SPWorkflowCollection workflows = item.Workflows;
foreach (SPWorkflow workflow in workflows)
{
SPWorkflowTaskCollection tasks = workflow.Tasks;
foreach (SPWorkflowTask task in tasks)
{
if (task[SPBuiltInFieldId.WorkflowVersion].ToString() != "1")
{
task[SPBuiltInFieldId.WorkflowVersion] = 1;
task.SystemUpdate();
}
}
}
}
}
}
}
Happy Coding :)
