c# - ASP.NET MVC returns corrupted file with wrong size -


i have problem - asp.net mvc returns file wrong size, therefore corrupted , cant open it. files on server , can open them, problem in returning , downloading files, also, files corrupted when downloaded, , files good. , on rare occasions, files, downloads in wrong size, gets downloaded in correct size. file sizes 500kb. code wasnt changed long time, , started return files wrong sizes. code simple:

public actionresult getfile(string filename) {     var contenttype = "image/jpeg";     if (system.io.file.exists(path.combine("c:\myfilesdirectory", filename)))     {         return this.file(path.combine("c:\myfilesdirectory", filename), contenttype, filename);     } }

c++ - Difference between pre and post decrement in recursive function argument -

i have following sample code used pre-decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(--c); cout << c << endl; return; } } this function give output input 4 : dp3 dp2 dp1 dp0 0 1 2 3 but when use post decrement void function(int c) { if(c == 0) { return; } else { cout << "dp" << c << endl; function(c--); cout << c << endl; return; } } output goes in infinite loop dp4 can explain me in detail why happens ? this happens because function(c--) called same value of c , when finishes c decremented. recursively called, hence called same value no chance of return , hit stack overflow error. assume this, int x = 1, y = 0; y = x++ result y == 1 , x == 2. if y = ++x , bot x , y 2.
