[英]C# - using string contains with string array
I have a question regarding C#, strings and arrays. 我对C#,字符串和数组有疑问。 I've searched for similar questions at stack overflow, but could not find any answers. 我在堆栈溢出时搜索了类似的问题,但找不到任何答案。
My problem: 我的问题:
I have a string array, which contains words / wordparts to check file names. 我有一个字符串数组,其中包含单词/ wordparts来检查文件名。 If all of these strings in the array matches, the word is "good". 如果数组中的所有这些字符串都匹配,则该单词为“good”。
String[] StringArray = new String[] { "wordpart1", "wordpart2", ".txt" };
Now I want to check if all these strings are a part of a filename. 现在我想检查所有这些字符串是否是文件名的一部分。 If this checkresult is true, I want to do something with this file. 如果此结果为真,我想对此文件执行某些操作。 How can I do that? 我怎样才能做到这一点?
I already tried different approaches, but all doesn't work. 我已经尝试过不同的方法,但一切都行不通。
ie 即
e.Name.Contains(StringArray)
etc. 等等
I want to avoid to use a loop (for, foreach) to check all wordparts. 我想避免使用循环(for,foreach)来检查所有的字部分。 Is this possible? 这可能吗? Thanks in advance for any help. 在此先感谢您的帮助。

Thanks to LINQ
and method groups conversions, it can be easily done like this: 感谢LINQ
和方法组转换,它可以像这样轻松完成:
bool check = StringArray.All(yourFileName.Contains);
Similar question: Using C# to check if string contains a string in string array 类似的问题: 使用C#检查字符串是否包含字符串数组中的字符串
This uses LINQ: 这使用LINQ:
if(stringArray.Any(stringToCheck.Contains))
This checks if stringToCheck contains any one of substrings from stringArray. 这将检查stringToCheck是否包含来自stringArray的子字符串中的任何一个。 If you want to ensure that it contains all the substrings, change Any to All: 如果要确保它包含所有子字符串,请将Any更改为All:
if(stringArray.All(s => stringToCheck.Contains(s)))
