C# unassigned local variable error

Question

I am new to C#. I am trying to complile the following program but it throws an error given at the end: I know I am making a silly mistake. Any help would be much appreciated:

static void Main(string[] args) {

        IntPtr hCannedMessages = CannedMessagesInit();

        using (StreamReader sr = new StreamReader(CANNED_MESSAGE_FILE))
        {
            String line, sub;
            all_integer_IDs[] myobjarray;// = new all_integer_IDs[10];
            for (int c = 0; c < 10; c++)
            {
                myobjarray[c] = new all_integer_IDs();

            }
                line = sr.ReadLine();
                Console.WriteLine(line);

                if (line.Length > 15)
                {
                     sub = line.Remove(line.IndexOf(' ', 2));
                     Console.WriteLine("{0} \n",sub);

    myobjarray[0].setvalues((int)sub[2], (int)sub[3], (int)sub[4], (int)sub[5]);

Console.WriteLine("{0}, {1}, {2}, {3}", myobjarray[0].m_messageID, myobjarray[0].m_messagetype, myobjarray[0].m_classID, myobjarray[0].m_categoryID); }

               Console.Read();
            sr.Close();
        }

    }
}

}

And the class is in Class1.cs file in the same project and is as follows:

public class all_integer_IDs {

    public all_integer_IDs() 
    {

        setvalues(0, 0, 0, 0);

    }

    ~all_integer_IDs()
    {
    }

    public void setvalues (int messageID, int messagetype, int classID, int categoryID)
    {
        this.m_messageID = messageID;
        this.m_messagetype = messagetype;
        this.m_classID = classID;
        this.m_categoryID = categoryID;
    }

     public int m_messageID;
     public int m_messagetype;
     public int m_classID;
     public int m_categoryID;

}

The error is as follows: Use of unassigned local variable 'myobjarray' at line 55 which is copied and pasted below: myobjarray[c] = new all_integer_IDs();

Thanks, Viren

You have not allocated space for myObjarray. You need to allocate it

Use:

all_integer_IDs[] myobjarray = new all_integer_IDs[10];
for (int c = 0; c < 10; c++)
{
    myobjarray[c] = new all_integer_IDs();
}

at line 55.

And please use PascalCase for class names (in your case, AllIntegerIDs). Other developers will thank you for that

--EDIT, my bad. Corrected the way to call it. Please try the following
