从Active Directory返回值

本文关键字:返回值 Directory Active | 更新日期: 2023-09-27 18:26:23

首先我想说我是编程新手。我在Visual Studio中创建了一个表单,其中有一个名为tEmailAddress的文本框和一个按钮bExport。当我把我的用户名放在tEmailAddress字段并按下按钮时,我希望它显示一个带有AD.显示名称字段的消息框

由于缺乏C#知识,我无法得到想要的结果。没有错误,当我点击按钮时,消息框中不会返回任何内容。请告知。

                else
                {
                    return "Unknown User";
                }
            }
            catch (Exception ex)

                return "";
            }
        }

        public Form1()
        {
            InitializeComponent();
        }

        private void pictureBox1_Click(object sender, EventArgs e)
        {
        }

        private void Form1_Load(object sender, EventArgs e)
        {
        }

        private void bExport_Click(object sender, EventArgs e)
        {
            if (tEmailAddress.Text != "")
            {
                string account = tEmailAddress.Text.ToString();
                FindName(account);
            }
        }
}
}

从Active Directory返回值

FindName返回一个字符串,但您永远不会在任何地方使用它

string result = FindName(account);

然后,您可以根据需要在bExport_Click方法中使用局部变量result

更改bExport_Click以显示消息

    private void bExport_Click(object sender, EventArgs e)
    {
        if (tEmailAddress.Text != "")
        {
            string account = tEmailAddress.Text.ToString();
            MessageBox.Show(FindName(account));
        }
    }
