c# - 'int' does not contain a definition and no extension method

I am facing the below error

'int' does not contain a definition for 'LeaveType' and no extension method 'LeaveType' accepting a first argument of type 'int' could be found (are you missing a using directive or an assembly reference?)

here is my code :

public DataSet GetLeaveRecord(int empID)
{
    DataSet ds = new DataSet();
    try
    {
        SqlCommand cmd = new SqlCommand("[p_GetLeaveRecord_LMS]", conn);
        cmd.CommandType = CommandType.StoredProcedure;
        SqlDataAdapter adapter = new SqlDataAdapter(cmd);
        cmd.Parameters.AddWithValue("@LeaveType", empID.LeaveType);
        cmd.Parameters.AddWithValue("@IdEmployee", empID.EmployeeId);
        cmd.Parameters.AddWithValue("@DateFrom", empIDd.DateFrom);
        cmd.Parameters.AddWithValue("@DateTo ", empID.DateTo);
        cmd.Parameters.AddWithValue("@Reason", empID.Reason);
        if (conn.State == ConnectionState.Closed)
        {
            conn.Open();
        }
        adapter.Fill(ds);
    }
    catch (Exception e)
    {
        throw e;
    }
    finally
    {
        if (conn.State == ConnectionState.Open)
        {
            conn.Close();
        }
    }
    return ds;
}

You are passing empID as an int type parameter and later you are using it as a type in your parameters. For example.

 cmd.Parameters.AddWithValue("@LeaveType", empID.LeaveType);

I believe you have to pass your object probably of EmployeeLeave type in your method

GetLeaveRecord(int empID)

Or you may get your object based on the ID in your method and then use that in your parameters
