Course.cshtml

Question

即使我选择了正确的日期值，我也无法弄清楚为什么我会收到此错误。我还希望当用户点击创建课程时，日期应该自动填写。

“SqlDateTime溢出。必须在1/1/1753 12:00:00 AM和12/31/9999 11:59:59 PM之间”

Answer 1

你有：

    var contentItem = _contentManager.New("Course");
    _contentManager.Create(contentItem, VersionOptions.Draft);
    dynamic model = _contentManager.UpdateEditor(contentItem, this);
    _contentManager.Publish(contentItem);

.Create()调用为contentItem生成INSERT语句。然后，对该项进行的其他更改将生成UPDATE语句。

在调用.Create()的时间点，您的对象的DateTime字段中仍然包含零。这就是SQL Server Compact无法创建项目的原因。您需要在此之前填写默认值。
