                  LogMessage(String.Empty);

                  saveFileDialog1.Filter = "XML files (*.xml)|*.xml";
                  saveFileDialog1.InitialDirectory = Application.StartupPath + "\\ SavedTest\\";

                  if (saveFileDialog1.ShowDialog() == DialogResult.OK)
                  {

                      foreach (Test t in _AllTests)
                      {

                          {
                              LogMessage("Saving " + file + "...");
                              TestToXML(t, file);
                              LogMessage("Saved Successfully.");
                          }

Could you please provide the following details,

1. every time you will save the same content
2. Is it a log file
3. File Name is fixed

1-no i am not saving the same content there is different information is added every time in that list named as _AllTests i m taking my desired one test from that list
2- no its not a log file its and xml file for one test information is there actually it is a load test software and in which i can make different types of test samples and can save them in xml file so later on i can load them as it is and can use it
3- in this code file name is not fixed it is taken out from savefiledialge whatever user input at savefiledialoge it will be the name of that file

It sounds as if you need the savefiledialog to find out the name of the file?? If the filename for each test cannot be derived from the name of the test in your list then you will always need the dialog. However, I will post a solution that assumes you can work out what the file is called

You could try something like this - note that it assumes you can work out what the filename should be...

C#

if (_AllTests.Count > 0)
{
    // Just clear already present message
    LogMessage(String.Empty);
    saveFileDialog1.Filter = "XML files (*.xml)|*.xml";
    saveFileDialog1.InitialDirectory = Application.StartupPath + "\\ SavedTest\\";

    foreach (Test t in _AllTests)
    {
        if (t._testName == tabControl2.SelectedTab.Text)
        {
            DialogResult d = DialogResult.Cancel;
            FileInfo fi = new FileInfo(Application.StartupPath + "\\SavedTest\\" + t._testName);
            // amend the above line to whatever the file name should be
            if (fi.Exists())
                d = DialogResult.OK;
            else
                d = saveFileDialog1.ShowDialog         
            if(d == DialogResult.OK)   
            {
                LogMessage("Saving " + file + "...");
                TestToXML(t, file);
                LogMessage("Saved Successfully.");
            }
        }
    }
}
