C# mvc按钮值单击不工作
在过去的几天里，我一直在解决一个问题，这让我很困惑。在这个表单中，我有两个文件上传输入，三个按钮，一个值为create、cancel和populate。用户浏览并选择一个文件，点击上传按钮，其提交值在我的操作方法“我保存文件”中填充，有一个静态类，使用状态机yield等和一些json序列化来解析数据，并将文件保存在appdata/uploads文件夹中。当他们点击cancel时，我执行一些功能，当他们点击create时，我不解析数据，只保存它。所有按钮输入在此页面上发布到相同的操作方法。所发生的是，在本地机器上，在我的服务器上的测试环境中，一切都很完美，似乎填充例程甚至没有运行。我甚至在异常表中添加了一个try-catch和log，但没有任何效果。我无法在测试环境中调试。更不用说解析了，如果用户选择了一个文件并点击了o populate，它会首先检查文件格式是否正确，我试图通过附加一个无效的格式抛出一个异常，但它甚至没有捕捉到。有趣的是，在同一操作方法中单击“保存”按钮，如果附加了无效文件，我的错误处理会捕获错误。我只是感到困惑。请建议C# mvc按钮值单击不工作,c#,asp.net-mvc-3,razor,C#,Asp.net Mvc 3,Razor,在过去的几天里，我一直在解决一个问题，这让我很困惑。在这个表单中，我有两个文件上传输入，三个按钮，一个值为create、cancel和populate。用户浏览并选择一个文件，点击上传按钮，其提交值在我的操作方法“我保存文件”中填充，有一个静态类，使用状态机yield等和一些json序列化来解析数据，并将文件保存在appdata/uploads文件夹中。当他们点击cancel时，我执行一些功能，当他们点击create时，我不解析数据，只保存它。所有按钮输入在此页面上发布到相同的操作方法。所发生的

Now the controller action method as follows:
[HttpPost]
public ActionResult Create(RunLogEntry runLogEntry, String ServiceRequest, string Hour, string Minute, string AMPM,
string submit, IEnumerable<HttpPostedFileBase> file, String AssayPerformanceIssues1)
{
if (submit == "Create")
{
if (file.ElementAt(0) != null && !file.ElementAt(0).FileName.Contains("json"))
{
ModelState.AddModelError(string.Empty, "Please attach a valid .JSON file for Load List selection");
}
if (file.ElementAt(1) != null && !file.ElementAt(1).FileName.Contains("out"))
{
ModelState.AddModelError(string.Empty, "Please attach a valid .OUT file for Load List selection");
}
}
if (submit == "Populate")
{
try
{
if (file.Count() > 0)
{
foreach (var modelValue in ModelState.Values)
{
modelValue.Errors.Clear();
}
if (file.ElementAt(0) != null && !file.ElementAt(0).FileName.Contains("json"))
{
ModelState.AddModelError(string.Empty, "Please attach a valid .JSON file for Load List selection");
}
else if (file.ElementAt(0) != null)
{
//If users are attaching another file, delete previous one
if ((System.IO.File.Exists(runLogEntry.LoadListStoredFileName)))
System.IO.File.Delete(runLogEntry.LoadListStoredFileName);
//Save LoadList File:
DateTime uploadDate = DateTime.Now;
string destinationPath = string.Format("{0}\\{1}\\{2}\\{3}\\", Server.MapPath("~/App_Data/uploads"), uploadDate.ToString("yyyy"), uploadDate.ToString("MMM"), uploadDate.ToString("dd"));
if (!Directory.Exists(destinationPath))
Directory.CreateDirectory(destinationPath);
}
}
将记录器添加到应用程序中，例如log4net，并观察这里到底发生了什么。
您有几个同名的标记。它是否可能引发一些副作用？是的，由于html 4 iis，它在服务器上无法正确呈现
