C# 从Active Directory C显示缩略图照片#
使用C#MVC 5从搜索中提取active directory中的数据。其中一个我需要它来拉缩略照片 因此，我的LDAP连接捕获初始数据，并成功地将缩略图转换为字节[]，至少看起来像是调试完成的。然后，当我尝试将字节数组转换为图像时，我得到一个“参数无效”错误 这是我的控制器：C# 从Active Directory C显示缩略图照片#,c#,asp.net,active-directory,ldap,C#,Asp.net,Active Directory,Ldap,使用C#MVC 5从搜索中提取active directory中的数据。其中一个我需要它来拉缩略照片 因此，我的LDAP连接捕获初始数据，并成功地将缩略图转换为字节[]，至少看起来像是调试完成的。然后，当我尝试将字节数组转换为图像时，我得到一个“参数无效”错误 这是我的控制器： [HttpPost] public ActionResult Index(string userName, string searchFilter) { /**********Establish Connec

编辑：它是十六进制格式的0x00，这与此有关吗？使用LDAP时，我以base64格式存储小图片。是的-它需要更多的空间，但解析速度非常快，我没有这样的问题。
Bitmap.FromStream的帖子，你也可以看看它，它可能会帮助你朝着正确的方向前进。我尝试创建一个新实例，不走运：（你找到答案了吗？我自己解决了。当图像转换为base64字符串时，它转换了一些额外的信息。我将前9个字符（或更多，不记得了）进行了子字符串，然后它就工作了。
