index out of range exception??

error code:

if (!Convert.IsDBNull(reader["Name"]))
username = reader["Name"].ToString();


2. source code:

public bool LoginUser(string username,string pwd)
{

bool exists = false;
SqlParameter[] parms = new SqlParameter[2];
parms[0] = new SqlParameter("@name", SqlDbType.NVarChar, 100);
parms[1] = new SqlParameter("@password", SqlDbType.NVarChar, 100);
parms[0].Value = username;
parms[1].Value = pwd;
SqlDataReader reader = DbTools.ExecuteReader("LoginUserProce", parms);

if (reader.Read())
{
exists = true;
if (!Convert.IsDBNull(reader.GetValue(2)))???????????????
username = reader.GetValue(2).ToString();
if (!Convert.IsDBNull(reader["password"]))
pwd = reader["password"].ToString();

}
reader.Close();
return exists;




}

索引超范围。

reader.GetValue(2)

改为

reader.GetValue(1)
