Question

I have declared my int[] as follows

int[] iroleID = new int[] { };

My code for getting the values from database and assigning to iroleid is as follows

if (oAuthenticate.getTaskID(out m_oDataSet1, "uspgetTaskID"))
{
  for (int iTaskid = 0; iTaskid < m_oDataSet1.Tables[0].Rows.Count; iTaskid++)
  {
   iroleID = Convert.ToInt32(m_oDataSet1.Tables[0].Rows[iTaskid]["RoleID"].ToString());
   strTaskID = m_oDataSet1.Tables[0].Rows[iTaskid]["TaskID"].ToString();
   arrTaskID.Add(strTaskID);
   }
}

But i am getting an error as mentioned Cannot implicitly convert type 'int' to 'int[]' can any one help me

And no surprise here. Look at

iroleID = Convert.ToInt32(...);

Convert.ToIn32 results in an int just like the compiler claims.
Either do something like:

if (oAuthenticate.getTaskID(out m_oDataSet1, "uspgetTaskID"))
{
    var iroleID = new int[m_oDataSet1.Tables[0].Rows.Count];
    for (int iTaskid = 0; iTaskid < m_oDataSet1.Tables[0].Rows.Count; iTaskid++)
    {
        iroleID[iTaskid] = Convert.ToInt32(m_oDataSet1.Tables[0].Rows[iTaskid]["RoleID"].ToString());
        /* ... */
    }
}

or rethink your algorithm.

PS: I can hardly tell you what exactly to do as you don’t show what the purpose of iRoleID is.
