如何读取仅今天创建的子文件夹中的 CSV 文件

Question

1.我有一个根位置（\Wna\sv_prod_01\USERS\Results\thorn-prod）在这个位置有 500 个文件夹，其中 20 个文件夹仅在今天创建，每个文件夹名称都以单词 PREBATCH 开头。

2.我关心的是如何从名为 PREBATCH 的 20 个文件夹中计算 csv

这是我尝试过的：

            DateTime today = DateTime.Now.Date;
            var directoryInfo = new System.IO.DirectoryInfo(@"\\\\\Wna001\sv_prod_01\USERS\Results\thorn-prod\");
            int directoryCount = directoryInfo.GetDirectories().Where(x => x.CreationTime.Date == today || x.LastWriteTime == today).Count();====this code is used to count the file which generated today only 

            string[] dirs = Directory.GetDirectories(@"\\\\\Wna001\sv_prod_01\USERS\Results\thorn-prod\", "*PREBATCH*"); ====this code is used to read the folder which start with word PREBATCH

            foreach (string dir in dirs)
            {
                int directoryCount1 = Directory.GetFiles("*.csv");
            }

Answer 1

您可以使用SearchOption.AllDirectories 选项查看文件夹的所有目录，

像这样更改代码，

    int count = 0;

    string[] dirs = Directory.GetDirectories(@"\\\\\Wna001\sv_prod_01\USERS\Results\thorn-prod\", "*PREBATCH*", SearchOption.AllDirectories);
    foreach (string dir in dirs)
    {
        var csvFiles = Directory.GetFiles(dir,"*.csv");
        foreach (var file in csvFiles)
            {
                 if(File.GetCreationTime(file) > DateTime.Now.Date)
                 {
                     count ++;
                 }
            }            
    }

注意：你的根目录是\\Wna001\sv_prod_01\USERS\Results\
