c# - Access to the path is denied after Assembly.Loadfile -


I create the web file app (.exe) and upload file (.exe) to get the assembly version ), But after the assembly. Because of the file error, I can not remove the file. Please explain to me this problem. 

  Protected Zero Upload BT_ Click (Object Sender, EventArgs e) {if (FileUpload1.HasFile) {try {/ ** file to TMP ** / Save string file name = FileUpload1.PostedFile .FileName; If (Directory.Exists (Server.MapPath ("~ / FilesUploaded / tmp")) (FileUpload1.PostedFile.SaveAs (Server.MapPath ("~ / FilesUploaded / tmp /" + filename));} Else {Directory. CreateDirectory (Server.MapPath ("~ / FilesUploaded / tmp"); FileUpload1.PostedFile.SaveAs (Server.MapPath ("~ / FilesUploaded / tmp /" + file name));} ** ** Get the assembly version ** / Assembly Access = assembly.loadfile (server.mappath ("~ / FilesUploaded / tmp /" + file name)); string version = ultra.GETName () .Version.ToString (); DirectoryInfo di = new DirectoryInfo (Server. MapPath ("~ / FilesUploaded / tmp"); FileInfo [] Fi = D. for gatefile (for int i = 0; i    
 
 
     
  1.  file Lock is because you loaded it into memory.  
  2.  Loading unchecked executables in memory on your web server is a huge security hole Do not do this! Seriously you do not know that in that file What is it?   
     Instead of Use:  
      var version = AssemblyName.GetAssemblyName (Server.MapPath ("~ / FilesUploaded / tmp /" + filename)); Version;

Java - Error: no suitable method found for add(int, java.lang.String) -

I'm in the middle of homework work and I'm stuck. At this point in my code, I think that I should have a GUI window that opens and allows me to type "inserted text number". Notice is not going anywhere but at this point, If I pass through the problem then it will be in a linked list. I am getting two of the same error for the lines. Add (index, element); And I can not seem to get past it, there is no suitable method for the error "add (int, java. string string)". Code is below, please advise.

c++ - static template member variable has internal linkage but is not defined -

Yes, I know, there is a question with almost the same title, but it refers to a different situation. Error message) In my case, I have a .cpp file with a big named designation name (implementation details). There is a property class template with a static data member in that name space, which I need to access from outside the unknown namespace. I give it a little bit of meat: file.hpp namespace Bar {template & lt; Typename A & gt; Struct foo {static_assert (is_same & lt; a, float & gt; :: value} is_same & lt; a, double>: value, ""); Fixed zero set_static_var (a const & x); // ...}; } and file.cpp namespace {template & lt; Typename A & gt; Struct foo_traits {// supports the implementation of several static code bars: foo & lt; & Gt; Fixed A data; }; The template's & lt; & Gt; Float foo_traits & lt; Float & gt; :: datum; // No change if this is in the global namespace template & lt; & Gt; Doub...
