Question

我创建了一个工作流来创建任务并使用自定义infopath表单批准该任务。单击“批准/拒绝”按钮时，任务表单会将XML异常提升为

“日期”是一个意外的标记，预期的标记是“=”。

下面我列出了例外的堆栈跟踪

Server Error in '/' Application.

'Date' is an unexpected token. The expected token is '='. Line 1, position 22.

 Description: An unhandled exception occurred during the execution of the current web request.

Please review the stack trace for more information about the error and where it originated in the code.

试试这可能有用......

您必须在task create属性中具有扩展属性声明。只需在可用空间中添加 x0020 即可。代码可能看起来像

SPTaskCreate_TaskProperties.ExtendedProperties["Start_x0020_Date"] = DateTime.Now;

而不是

SPTaskCreate_TaskProperties.ExtendedProperties["Start Date"] = DateTime.Now;
