Question

I have use for loop in my code and but its showing error of Use of unassigned local variable.

Here is my code:

public List<CustomTypeLayer.EmployeeLeave> GetLeaveRecord(int emplid)
{
    DataSet ds = objLMSRepository.GetLeaveRecord(emplid);
    List<EmployeeLeave> leavelist = new List<EmployeeLeave>();
    if (ds != null && ds.Tables.Count > 0 && ds.Tables[0].Rows.Count > 0)
    {
        for (int k; k < ds.Tables[0].Rows.Count; k++)
        {
            DataRow dr = ds.Tables[0].Rows[k];
            EmployeeLeave leave = new EmployeeLeave();
            leave.DateFrom = Convert.ToDateTime(dr["dt_from"]);
            leave.DateTo = Convert.ToDateTime(dr["dt_to"]);
            leave.EmployeeId = Convert.ToInt32(dr["EmployeeID"]);
            leave.Reason = Convert.ToString(dr["txt_reason"]);
            leave.LeaveType = (LeaveReason)Enum.Parse(typeof(LeaveReason), dr["id_leave_type"].ToString(), true);
            leavelist.Add(leave);
        }
    }
    return leavelist;
}

The error is in the for loop in k. You can see in for loop I have initialized k with int k.

Answer 1

You need to give k an initial value, like

for (int k = 0; k < someValue; k++)
{
    // Do stuff.
}

I hope this helps.
