Why i'm getting exception: Closed stream access exception while saving Bitmap ? Where does it come from ? What Bitmap ? Why i can't catch the exception ?

i have code in bottom label11 assign text:

private void getissuesnumber()          {              using (webclient client = new webclient())              {                  client.downloadfile("https://test/issues/26", @"c:\test\issues.html");                  client.downloadfile("https://test/issues", @"c:\test\main.html");              }                  using (streamreader reader = new streamreader(@"c:\test\issues.html"))              {                  try                  {                      string line = string.empty;                      while ((line = reader.readline()) != null)                      {                          if (line.contains("comments"))                          {                              if (line.any(char.isdigit))                              {                                  this.line = line;                                  numberofcomments = int32.parse(this.line.substring(17, 2));                              }                          }                          if (line.contains("opened this"))                          {                              opened = line;                              gettime(opened);                          }                                                }                  }                  catch (exception err)                  {                      error = err.tostring();                  }              }              label2.text = numberofcomments.tostring();                using (streamreader reader = new streamreader(@"c:\main\main.html"))              {                                        string line = string.empty;                      while ((line = reader.readline()) != null)                      {                          if (line == null || line != "")                          {                              if (line.contains("open"))                              {                                  issuesopened = line;                                  label10.text = issuesopened.tostring();                              }                              if (line.contains("closed"))                              {                                  try                                  {                                      issuesclosed = line;                                      label11.text = issuesclosed.tostring();                                  }                                  catch (exception err)                                  {                                      error = err.tostring();                                  }                              }                          }                      }                                                  }              }

if don't assign label11 not using ok.

if don't use line: 

label11.text = issuesclosed.tostring();

then when running program see label11

but if i'm using line assigning label11 see when running program is:

what bitmap ? don't use bitmap/s in code.

why can't catch exception using try , catch ? didn't stop on catch part used breakpoint.

i closed shut down whole visual studio , tried run on , still same exception on label11.

i dragged form1 designer 2 new labels: label10 , label11 10 there no problems 11 see exception.

in variable line when label11.text.....in variable line there is:       15 closed

there spaces before 15.

what variable issuesclosed? i don't see defined anywhere.

have looked inside c:\main\main.html? line "closed stream access exception..." embedded inside somewhere?
