There are many ways to skin a Web page, and the simplest is usually to switch between CSS and CSS, which is usually written in an external CSS file. Then switching CSS is actually replacing the link href path in HTML. I searched the internet for the next.There are generally two ways:1. Put a holder control on the page. Then programmatically write the current user's style CSS link to the page.2. Over-reflection mechanism, set CSS style on a per-control basis.The above two ways are very troublesom

. NET provides excellent support for XML reading and writing, and provides many classes in the. NET Framework XML namespace to read and write XML files. When you need to read and write XML files, you can enter using system. xml at the top of the Code to tell the compiler and runtime environment that we need to use clas

Today, I encountered this problem and got depressed. Alas. The program runs properly just now. Suddenly, this error occurs.
I really don't know what's going on. The Internet is better. Baidu finally found a solution.
I used method 2 to solve my problem.
The error message is as follows:

. NET core usage configuration filesIn.

As for the problem of not being able to execute @Html Helper, I offer another solution, but this can modify the source code, want to toss friends can try. In fact, this can also use a lot of custom methods, more flexible and convenient oh. After downloading the RAZORJS source code, you can directly modify the above and then recompile a DLL out, another way is to use its source
After the anti-compilation project file is opened with VS2010, a series of error prompts appear when you open the form:First case:"The designer cannot process the code for line 152th: base.

. NET is a language that is built on a virtual machine that generates the intermediate language of the MSIL directly, and then the. NET compiler JIT interprets the image as native code and delivers CPU execution. The intermediate language is easy to decompile, so study how to effectively protect DLL files. My approximate method is: Strong signature + obfuscation
Transform different languages with simple settings and references1, the new resource file resource.resx,vs2005 automatically put it in the App_GlobalResources folder;2, open the resource file, enter the common string, the file is a collection of some key/value, key used to do the reference of the identity, value is used to represent the value of the string; (you can see that Resource.resx is actually an XML file after saving)3, in the system for reference:
