调用从我的控制器索引视图时路径中具有非法字符 [英] Illegal characters in path when calling the index view from my controller

问题描述

我调用我的控制器之一的索引操作时收到一个ArgumentException，我不知道为什么。该错误消息是：

中的服务器错误'/'应用。

路径中具有非法字符。

  [ArgumentException的：路径中具有非法字符]
 System.IO.Path.CheckInvalidPathChars（字符串路径）+126
 System.IO.Path.Combine（PATH1字符串，字符串PATH2）+38
 

我不知道为什么会这样。这里是从控制器code：

 公众的ActionResult指数（）
    {
        变种glaccounts = db.GLAccounts.ToString（）;
        返回查看（glaccounts）;
    }
 

解决方案

模糊性来自于事实，你正在使用字符串的型号。这种不确定性就可以解决这样的：

 公众的ActionResult指数（）
{
    变种glaccounts = db.GLAccounts.ToString（）;
    返回查看（（对象）glaccounts）;
}
 

或

 公众的ActionResult指数（）
{
    对象glaccounts = db.GLAccounts.ToString（）;
    返回查看（glaccounts）;
}
 

或

 公众的ActionResult指数（）
{
    变种glaccounts = db.GLAccounts.ToString（）;
    返回视图（指数，glaccounts）;
}
 

注意投反对挑选适当的方法重载因为已经有一个查看方法，需要其重新$ P $字符串参数psents视图名称，以便您不能把任何你想它=>如果它是一个字符串，它必须是视图的名称，这种观点必须存在。

I am receiving an ArgumentException when invoking the index action of one of my controllers and I am not sure why. The error message is the following:

Server Error in '/' Application.

Illegal characters in path.

[ArgumentException: Illegal characters in path.]
 System.IO.Path.CheckInvalidPathChars(String path) +126
 System.IO.Path.Combine(String path1, String path2) +38

I am not sure why this is happening. here is the code from the controller:

    public ActionResult Index()
    {
        var glaccounts = db.GLAccounts.ToString();
        return View(glaccounts);
    }

解决方案

The ambiguity comes from the fact that you are using string as model type. This ambiguity could be resolved like this:

public ActionResult Index()
{
    var glaccounts = db.GLAccounts.ToString();
    return View((object)glaccounts);
}

or:

public ActionResult Index()
{
    object glaccounts = db.GLAccounts.ToString();
    return View(glaccounts);
}

or:

public ActionResult Index()
{
    var glaccounts = db.GLAccounts.ToString();
    return View("Index", glaccounts);
}

Notice the cast to object to pick the proper method overload as there is already a View method which takes a string argument which represents the view name so you cannot throw whatever you want to it => if it's a string it must be the name of the view and this view must exist.
