c# - Compare all items from a Collection with items from another Collection? -

-

अरे, मेरे पास यह कोड है: 

  ArrayList सरणी = नया ArrayList (); arrayList.add ( "एक"); arrayList.add ( "दो"); arrayList.add ( "तीन"); सूची के & lt; DataRow & gt; डेटा लिस्ट = गेटडाटालिस्ट (कुछ पैरामीटर);

अब मैं जांचना चाहता हूं कि क्या arrayList में डेटा लिस्ट के तत्व हैं स्ट्रिंग आईटैरेआर [0] में डेटा लिस्ट में है क्या ऐसा करने के लिए एक अच्छा लघु कोड संस्करण है?

धन्यवाद: -)

.NET 3.5 में यह जांचने के लिए कि एक सूची में से सभी तत्व अन्य सूची में समाहित हैं: 

  bool परिणाम = सूची। सभी (x = & gt; डेटा लिस्ट.संसाधन (x));

या आप इसे और के संयोजन के द्वारा कर सकते हैं: 

  bool परिणाम =! सूची। (डेटा लिस्ट) को छोड़ दें। कोई भी ();

अपने उदाहरण में आप एक ArrayList का उपयोग कर रहे हैं। आपको इन विधियों का उपयोग करने के लिए इसे सूची & lt; ऑब्जेक्ट & gt; या सूची & lt; स्ट्रिंग & gt; में बदलना चाहिए अन्यथा आप arrayList.Cast & lt; ऑब्जेक्ट & gt; () । 

  bool परिणाम = arrayList.Cast & lt; ऑब्जेक्ट & gt; ()। सभी (x = & gt; dataList) लिख सकते हैं। शामिल (x));

Obfuscating Python code? -

-
I'm looking for a way to hide my Python source code. print "Hello World!" How can I encode this example so that it is not human-readable? I have been asked to use Base 64 but I'm not sure how. itemprop = "text"> It is limited only, first level ambiguous resolution, but has built-in: byte-code in Python Is a compiler for: dragon-o-m py_compile & lt; Your program.py & gt; creates a .pyo file with a byte-code, and where the docstrings are removed, etc. You can rename .pyo with the .py extension, and python & lt; Your program.py & gt; runs as your program, but it does not have your source code. PS : If your program blur modules like this, you need to rename them with the .pyc suffix (I Not sure it will not break a day), or you can work with .pyo and run them with python -o ... .pyo ( Import should work). This will allow dragon to search your modules (otherwise, Python looks for the .py module).
