PowerShell GUI创建AD用户异常：点击保存按钮无法读取文本框数据求助

嘿，我来帮你搞定这个问题！你的脚本里有两个核心问题导致点击「Speichern」按钮后需要手动输入姓氏，咱们一步步来修正：

问题原因分析 #

1. 变量赋值时机不对
   你在脚本初始化阶段就把文本框的内容赋值给了$addv、$addn这些变量，比如：

   $addv = $Textboxvorname.Text
   

   这时候用户还没在文本框里输入任何内容，这些变量的值都是空字符串。当点击按钮执行New-ADUser时，用的还是这些空值，PowerShell自然会提示你手动补全必填的Surname参数。

2. 参数语法错误
   在New-ADUser的调用里，你写成了-Givenname = $addv和-Surname =$addn，这里的等号是多余的！PowerShell的参数格式是-参数名 参数值，不需要加等号，否则会被当成参数值的一部分，导致参数无法正确识别。

修正后的完整脚本 #

我已经帮你把这两个问题修复了，还加了简单的输入验证和错误处理，避免空输入或创建失败的情况：

额外优化说明 #

• 用.Trim()去除输入内容前后的空格，避免不必要的空白导致的问题
• 增加输入验证，确保所有必填字段都被填写，并用弹窗提示用户
• 加入try-catch块捕获创建用户时的错误，方便排查问题
• 给New-ADUser添加-Enabled $true参数，默认启用新用户（可根据需求调整）
