Path.Combine is handy, but is there a similar function in the .NET framework for URLs? I'm looking for syntax like this: Url.Combine("http://MyUrl.com/", "/Images/Image.jpg") which would return: "http://MyUrl.com/Images/Image.jpg" Uri has a constructor that should do this for you: new Uri(Uri baseUri, string relativeUri) Here's an example: Uri baseUri = new Uri("http:/
Path.Combine非常方便，但是.NET框架中是否有类似的功能？ 我正在寻找这样的语法： Url.Combine("http://MyUrl.com/", "/Images/Image.jpg") 这将返回： "http://MyUrl.com/Images/Image.jpg" Uri有一个构造函数应该为你做这个： new Uri(Uri baseUri, string relativeUri) 这是一个例子： Uri baseUri = new Uri("http://www.contoso.com"); Uri myUri = new Uri(baseUri, "catalog/shownew.htm"); 您使用
I have a variable named like allowedZHs . ZH is a domain specific acronym. ZHs is its plural form. I would like to continue using that plural form. I find it much more expressive than the "correct" form " Zhs ". I tried to tell Code Analysis this by adding a Code Analysis Dictionary. This works fine for the singular form " ZH " but it doesn't work for the
我有一个名为allowedZHs的变量。 ZH是一个领域特定的首字母缩略词。 ZHs是它的复数形式。 我想继续使用这种复数形式。 我发现它比“正确”形式“ Zhs ”更具表现力。 我试图通过添加代码分析字典来告诉代码分析。 这适用于单数形式“ ZH ”，但它不适用于复数形式。 我仍然收到警告CA1704。 我尝试将它作为一个公认的词加入，并将其添加为首字母缩写词： <Dictionary> <Words> <Recognized>
This question already has an answer here: Finding the variable name passed to a function 16 answers 哈克方法，你可以通过Expression获得： string myVariable = string.Empty; Expression<Func<object>> expression = () => myVariable; string name = (expression.Body as MemberExpression).Member.Name; If you can access a variable by name, you already have its name, so type "MyVariab
这个问题在这里已经有了答案： 找到传递给函数的变量名称16个答案 哈克方法，你可以通过Expression获得： string myVariable = string.Empty; Expression<Func<object>> expression = () => myVariable; string name = (expression.Body as MemberExpression).Member.Name; 如果你可以通过名字访问一个变量，你已经有了它的名字，所以输入"MyVariable" 。 如果你重新分配了它，这是不可能的。
Why is VS 2012 showing the Type variable as an NullReferenceException when it also shows that it's value = "Retailer" . I've got a newborn, and I'm working on limited sleep, so I apologize if I'm missing something obvious here. The LoggedInUser.Employer object has been instantiated and this line works fine 1/2 of the time. But then it starts breaking. Not sure if th
为什么VS 2012在显示value = "Retailer"时显示Type变量为NullReferenceException。 我有一个新生儿，而且我正在进行有限的睡眠，所以如果我在这里错过了一些明显的东西，我很抱歉。 LoggedInUser.Employer对象已经被实例化，并且该行在1/2的时间内工作正常。 但随后它开始打破。 不知道这是否有帮助 - 需要睡眠... private string _type; public string Type { get { return _type; } s
My program has some settings built in which all have a User Scope. However when the program launches it only creates the AppName.exe.config file, which contains the settings . When saving a setting later on during runtime, it creates the user.config file (which previously didn't exist) in the AppData/Local/AppName/ location, but that file only contains the saved setting. Why does this ha
我的程序有一些内置的用户范围设置。 但是，当程序启动时，它只会创建包含设置的AppName.exe.config文件。 稍后在运行时保存设置时，会在AppData / Local / AppName /位置创建user.config文件（以前不存在），但该文件只包含保存的设置。 为什么会发生？ 为什么不创建user.config或在启动时使用它，如果它存在？ 从MSDN的应用程序设置体系结构： 应用程序范围的设置可以存储在machine.config或app.exe.config文件中。
I know there's a couple similarly worded questions on SO about permutation listing, but they don't seem to be quite addressing really what I'm looking for. I know there's a way to do this but I'm drawing a blank. I have a flat file that resembles this format: Col1|Col2|Col3|Col4|Col5|Col6 a|b,c,d|e|f|g,h|i . . . Now here's the trick: I want to create a list of all poss
我知道关于排列列表，有几个类似的措辞问题，但他们似乎并没有真正处理我正在寻找的东西。 我知道有办法做到这一点，但我画了一个空白。 我有一个类似于这种格式的平面文件： Col1|Col2|Col3|Col4|Col5|Col6 a|b,c,d|e|f|g,h|i . . . 现在有个诀窍：我想创建这些行的所有可能排列的列表，其中行中用逗号分隔的列表表示可能的值。 例如，我应该能够将表示上面的IEnumerable<string>作为行： IEnumerable<string>
After a socket has been setup, is it better practice to use read(2) and write(2) calls on the socket descriptor, or to associate a stream with the socket descriptor using fdopen(3) and then use stdio(3) functions? int sfd = socket(PF_INET, SOCK_STREAM, 0); // setup the socket using sfd FILE * stream = fdopen(sfd, "r+"); // use fprintf, fscanf, etc EDIT: I also unbuffer the stream setbuf(stream
在套接字建立之后，对套接字描述符使用read（2）和write（2）调用，或者使用fdopen（3）将一个流与套接字描述符相关联，然后使用stdio（3）函数？ int sfd = socket(PF_INET, SOCK_STREAM, 0); // setup the socket using sfd FILE * stream = fdopen(sfd, "r+"); // use fprintf, fscanf, etc 编辑：我也unbuffer流 setbuf(stream, NULL) 避免按照评论中提到的那样刷新它。 我一直在使用这种方法，因为它可以让我重新使用
I have a DTO coming from the Javascript client. When I try to send with deleteFromService the request object is empty (looks like it was just new-ed up). If I change the method to postToService the request object is populated properly. I am using the 3.9 API. I am at a loss here. Service: public object Post(Order request) { return _orderRepository.InsertOrder(request); } public objec
我有一个来自Javascript客户端的DTO。 当我尝试使用deleteFromService发送时，请求对象是空的（看起来像是刚刚新建的）。 如果我将方法更改为postToService ，请求对象正确填充。 我正在使用3.9 API。 我在这里不知所措。 服务： public object Post(Order request) { return _orderRepository.InsertOrder(request); } public object Delete(Order request) { _orderRepository.DeleteOrder(request.Uuid);
Here is a short program that reproduces the problem I just encountered. This was compiled under MS Windows 7 with .NET 4.0, just in case that makes a difference. using System; using System.Drawing; using System.Windows.Forms; // Compile with "csc /target:exe /out:comboboxbug.exe /r:System.dll /r:System.Drawing.dll /r:System.Windows.Forms.dll comboboxbug.cs" // in a Visual Studio command prompt
这是一个简短的程序，它重现了我刚刚遇到的问题。 这是使用.NET 4.0在MS Windows 7下编译的，以防万一。 using System; using System.Drawing; using System.Windows.Forms; // Compile with "csc /target:exe /out:comboboxbug.exe /r:System.dll /r:System.Drawing.dll /r:System.Windows.Forms.dll comboboxbug.cs" // in a Visual Studio command prompt. static class Program { [STAThread] static void Main()
My programmer's instinct would say that a character constant in c (eg: 'x') is encoded using the machine character set from the machine on which it is compiled. However, the following exerpt is from "The C Programming Language: ANSI C Edition" "A character constant is a sequence of one or more characters enclosed in single quotes, as in 'x'. The value of a ch
我的程序员的本能会说c中的字符常量（例如：'x'）是使用编译它的机器中的机器字符集进行编码的。 但是，以下exerpt来自“The C Programming Language：ANSI C Edition” “字符常量是用单引号括起来的一个或多个字符的序列，如'x'所示。只有一个字符的字符常量的值是机器字符集中执行时字符集的数值。 强调最后3个字。 任何人都可以解释为什么他们会说“在执行时”。 当然，字符值是以编译后的二进制（或ELF
