How do I check whether the file is empty or not? + 2 more questions about file path

1. Subj

2. How can I get a full path to a current directory?

3. How can I place some string in this path string in _HERE_:
"c:/some foler/more folders/myFileName_HERE_.ext"

1.)

Code:

---

public bool SomeClass::IsFileEmpty(string fileName)
{
    bool _ret = false;
    try
    {
        FileStream fs = File.OpenRead(strFileName);
        _ret = (fs.Length == 0);     
    }
    catch (Exception e)
    {
        throw new Exception("IsFileEmpty method exception", e);
    }
    return _ret;
}

2.)
Full path to the current directory or full path to the directory where your executable is stored???

Current dir:

Code:

---

string currentDir = System.AppDomain.CurrentDomain.SetupInformation.DynamicBase;

---

Path to the executable:

Code:

---

string path = System.AppDomain.CurrentDomain.SetupInformation.ApplicationBase;

---

3.)

Code:

---

public string SomeClass::AppendFileName(string path, string appendText)
{
    // you have to check if the path or appendText are valid (not null) and if the path is really path to the file before this code...
    string _ret = path.Substring(0, path.LastIndexOf('.')) +
        appendText + path.Substring(path.LastIndexOf('.'));
    return _ret;
}
