发送多个文档到打印机

Question

我在.net wpf中有一个要求。 部分图像格式为.gif或.jpg在本地文件夹中。 我已经准备了一个字符串列表，用于存储文件名称 我希望将按列表中的所有图像发送到打印机。

我已经搜索了Google，但对于Print文档，我们只能给出一个文件PrintFileName。

但我想为每个循环给每个文件名。任何人都可以解释它怎么可能？

谢谢..

Answer 1

问题主题是看起来像错误的... 的答案;

var filenames = Directory.EnumerateFiles(@"c:\targetImagePath", "*.*", SearchOption.AllDirectories) 
         .Where(s => s.EndsWith(".gif") || s.EndsWith(".jpg") || s.EndsWith(".bmp")); 
foreach (var filename in filenames) 
{ 
    //use filename 
}
