推荐答案

，假设您有Client和Server应用程序互相通信(如果没有，那么您的问题比屏幕截图传输要大)，然后只需使用客户端应用程序获取客户端"屏幕的副本，将其转换为某种类型的图像，然后通过现有的通信链接将其发送到服务器.

哪一部分给您带来了麻烦?

Assuming you have the Client and Server applications talking to each other (and if you don''t you have bigger problems than screen shot transfers), then just take a copy of the Client screen with the client application, convert it to an image of some type, and send it to the server via the existing communications link.

Which part of that is giving you problems?

我已经回答了几乎相同的问题. (什么，这是学校的作业，对于一组学生来说是相同的吗?！)

基本上，有一些变体:1)每个学生计算机上的自定义Windows服务； 2)每个学生计算机上的简单HTTP服务器； 3)每个学生计算机上带有Web应用程序的一些可用HTTP服务器.在情况(2)和(3)中，教师的UI可能只是可用的Web浏览器！

I already answered nearly the same question. (What, is that the school assignment, the same one for a group of students?!)

Basically, there are some variants: 1) custom Windows Service on each student''s computer, 2) simple HTTP server on each student''s computer, 3) some available HTTP server with Web application on each student''s computer. In cases (2) and (3) the teacher''s UI could be just an available Web browser!

Note: It does not have to be WPF.

创建多用户共享桌面会更好吗?

Wouldn''t it be better to create a multi user shared desktop?

I guess you could alter/enhance this software[^].

I guess that could be the ultimate "virtual teacher", or support tool :)
