如何从FileInfo []获得文件全名的完整目录，包括文件扩展名？ [英] How can i get from a FileInfo[] the file full name full directory including the file extension?

问题描述

这是代码：

FileInfo[] flist = d.GetFiles();
if (flist.GetLength(0) > 0)
{
    foreach (FileInfo txf in flist)
    {
        string fn = txf.FullName + txf.Extension;
    }
}

如果我只做全名，它将给我目录+文件名，但不带扩展名。
如果我正在这样做：字符串fn = txf.FullName + txf.Extension;扩展名是空的

If i'm doing only fullname it will give me the directory+file name but without the Extension. And if i'm doing it: string fn = txf.FullName + txf.Extension; Extension is empty ""

例如，我需要使它完整：c：\test.png
否则fn将包含：c： \temp\dir\testing.jpg

I need to get it full like this for exmaple: c:\test.png Or that fn will contain: c:\temp\dir\testing.jpg

完整目录路径+完整文件名+文件扩展名

Full directory path + full file name + the file name extension

推荐答案

根据文档， FileInfo 对象的全名字段包括完整路径，文件名和文件扩展名（ FileInfo 从 FileSystemInfo FullName $ c>）。因此，更像是负责创建这些文件的代码没有附加适当的扩展名（假设 d 是 DirectoryInfo ，而不是其他（也许是自制的）类。

According to the documentation, FullName field of a FileInfo object includes full path, file name and file extension (FileInfo inherits FullName from FileSystemInfo). So it is more like the code, which is in charge for creating these files, is not appending the proper extension (Assuming d is a DirectoryInfo and not other - maybe homemade - class).
