获取名称中不包含特定字符串的文件名 [英] Getting file name that doesn't contain particular string in its name

问题描述

假设在一个目录中我有几个.xml文件。其中一些文件的名称中包含_schema字符串。我想获取那些不包含此特定字符串的文件名。

Suppose in a directory I have few .xml file. Some of these file has "_schema" string in it's name.I want to get those file name that doesn't contain this particular string.

Directory.GetFiles(pathOfTable,".xml")

代码返回所有.xml文件名

This code return all .xml file name

Directory.GetFiles(pathOfTable,"_schema.xml")

此代码返回带有_schema字符串的所有文件名

但是，我需要那些不包含此字符串的文件名

this code return all file name with "_schema" string
But, I need those file name that does not contain this string

推荐答案

Directory.GetFiles 不包含NOT选项。

解决方法是将所有文件放在文件夹中，然后用字符串操作查询每个文件

Directory.GetFiles does not contain a NOT option.
The way to go about it is to get all files in folder, then "query" each of them with a string operation

string[] fileEntries = Directory.GetFiles(targetDirectory);

foreach(string fileName in fileEntries)
{

     if (!fileName.EndsWith("_schema.xml"))
          actions...

}

这样，如果文件名不包含这样的字符串，那么if语句将会启动。

That way, if the file name does not contain such string, the "if" statement will kick in.

作为c＃视图：

返回所有文件并使用列表处理算法或简单地使用linq进行任何后期处理

as c# view :
return all file and use list processing algorithms or simply use linq to any post processing

string[] fa = { "test_schemaoky", "farshad", "_schemafarshad", "saeidi" };
            List<string> fl = new List<string>();
            fl.AddRange(fa);
            List<string> f2=fl.FindAll(itm => itm.IndexOf("_schema")==-1);
