synchronization and lock statement

mehdi62b · February 4th, 2005, 02:57 PM

Hi Experts,
please look at this example,can someone tell me what is the scenario behind it,

Code:

class MyClass 
{
    private string m_sString = null;

    public MyClass()
    {
        m_sString = "Hello";
    }

    void GetString1()
    {
        lock (this)
        {
            return m_sString;
        }
    }

    void GetString2()
    {
        lock (m_sString)
        {
            return m_sString;
        }
    }
}

I know another thread can't access GetString1,I don't know what is the difference between lock(this) and lock(m_sString)?
Thanks in advance.

void GetString1()
    {
        lock (this)
        {
            return m_sString;
        }
    }
How Void function will return data..
