checking if a file exists

Question

User-2012457684 posted

I want to write some code to read the iis logfiles on  the server so clients can get some information.  The client will be able to pick a date range and get the infromation based on that.   To that end I want to check to see if the log file exists.   For some reason i am getting an erro and don't understand what is wrong

using System.IO;
....snip


[HttpPost]
public ActionResult Index(DateTime StartDate, DateTime EndDate)
{
    List<String> logList = new List<String>();
    foreach (DateTime day in EachDay(StartDate, EndDate))
    {
        string d = day.Day.ToString("00");
        string m = day.Month.ToString("00");
        string yr = day.Year.ToString().Substring(2);
        string logfile = "u_ex" + yr + m + d + ".log";
        logList.Add(logfile);
    }
            
    var processID = Request.ServerVariables["INSTANCE_ID"];
    string path = @"c:\inetpub\logs\logfiles\w3svc" + processID.ToString();
    if(Directory.Exists(path))
    {
                
        foreach(string log in logList)
        {
            string LogFile = path + @"\" + log;
            if (File.Exists(LogFile))
            {

            }
        }

                

    }


    return View();
}

shows the following in the Error List

'Controller.File(byte[], string)' is a method, which is not valid in the given context

As usual I don't understand what it is trying to tell me.

It's saying that Controller is an object, it has a method called File() and somewhere in code you're not using it as an object with a method.

That is in the controller   inside of the Index method

File is a class in System.IO  Exists is a method of the class

so it makes no damn sense

I found the answer    i needed to use 

 if (System.IO.File.Exists(LogFile))
{

}

I would say fully qualify it giving the namespace File really lives in maybe it will work.

            if (System.IO.File.Exists(LogFile))
            {

            }

I have been use the mvc controller to do that and I already use this for lightweight canoe paddles and it works

@using (Html.BeginForm("FileUpload", "Home", FormMethod.Post, new { enctype = "multipart/form-data" }))
{ 
 @Html.ValidationSummary();
 <ol>
 <li class="lifile">
 <input type="file" id="fileToUpload" name="file" />
 <span class="field-validation-error" id="spanfile"></span>
 </li>
 </ol>
 <input type="submit" id="btnSubmit" value="Upload" />
}
