    //Functionality : AutoComplete The DepartmentName
    ArrayList  arlSample = new ArrayList();
    arlSample = objDataAccess.GetSingleColumn("QRY_DeptName", prefixtext);

}

上面是bll文件代码。调用getsinglecolum函数

public ArrayList GetSingleColumn(string strQuery, params object[] objValueList)
{ 
    ArrayList arlData = new ArrayList();
    try
    {
        string strQry;
        strQry = ReadXmlvalue(strQuery, objValueList);
        cmdHrm = new OleDbCommand();
        cmdHrm.Connection = conHrmDb;
        if (conHrmDb.State == ConnectionState.Closed)
            conHrmDb.Open();
        cmdHrm.CommandText = strQry;
        drdHrm = cmdHrm.ExecuteReader();

        while (drdHrm.Read())
        {
            arlData.Add(drdHrm.ToString());
        }
        return arlData;
    }
    catch (Exception ex)
    {
        throw ex;
    }
    finally
    {
        if (conHrmDb.State == ConnectionState.Open)
            conHrmDb.Close();
    }
}

上面是dal文件代码。我想将字符串返回aspx.cs file..help plz

Answer 1

如果要将ArrayList转换为字符串数组，可以使用：

 IEnumerable<string> strings = arlSample.Cast<string>();
 string[] result = strings.ToArray();

如果你想连接所有元素，那么你可以返回一个你应该使用的字符串：

 string resultString = String.Concat(strings);

拆分arraylist并以字符串形式返回到arraylist的长度
