不确定问题出在哪里-文件上传正常，可以转到正确的文件夹，但是路径和文件名未存储在数据库中。
我想使用它，以便为上载的每个文档添加指向索引视图的链接。
在这方面我已经竭尽全力了2天了，在这方面的任何帮助都是很棒的。
致谢

答案 0 :(得分：0)
您似乎在ComputerInventory中因此在表中也缺少Path属性。您没有设置任何属性的路径。您如何期望将其保存在数据库中？
首先在表格中添加一列作为FilePath，更新Model ComputerInventory并设置此FilePath变量的路径
Class ComputerInventory()
{
public string FilePath { get; set; }
//other properties;
}
computerInventory.FilePath = path;
db.ComputerInventories.Add(computerInventory);
db.SaveChanges();
