tostring

问题 in my ASP.NET MVC project, I need to make the JavaScript implicite string representation to be current culture aware , in particular with decimal separators. For example: var nbr = 12.25; console.log(nbr); Here, the console.log(nbr) must display "12.25" in EN-US and "12,25" in fr-FR, without having to explicitly call the toString() method. Does anyone know a way to accomplish this please? 回答1: You are probably looking for toLocaleString(); : The toLocaleString() method returns a string with a

问题 The following code gives me the error (cannot add type Object to Stackpanel). How can I say .ToString() in XAML? <Window.Resources> <Style TargetType="{x:Type ListBoxItem}"> <Setter Property="Content"> <Setter.Value> <StackPanel Orientation="Horizontal"> <TextBlock Text="{Binding Path=FirstName}"/> </StackPanel> </Setter.Value> </Setter> </Style> </Window.Resources> <Grid> <ListBox x:Name="theCustomers"/> </Grid> binding in code-behind with ADO.NET Entity Framework: MainEntities db = new

问题 I am having an issue with the toString method in Java . Here's the run down... I have a database that I am querying. The query returns all of the members in the database, and I'd like to return these members as a string. Here's what I've done so far. In the Member class I have the following @Override public String toString() { return this.login_name + " (" + this.lastName + ", " + this.firstName + ")"; } Now, to get the members from the database and return them as an array of strings, here's

问题 I have an application with a lot of calls to Decimal.ToString(void). The default format is not what is needed. I could change these calls to one of the other Decimal.ToString overloads, but it would be nicer if I didn't have to. So, is there a way to specify a different format for the Decimal.ToString(void) method so that I don't have to modify any of the calls to this method? Update As the answer below indicates, it is possible to do what I want, but I should not do so as it is not good

问题 When debuggind java code in eclipse, if you click on one of the variable names, that object gets printed. The object's toString() method is used to print it. If some toString method has a side effect and I click on a variable of that type, will the side effects of its toString get applied (and doubtlessly mess everything up)? 回答1: I think you answered your own question. Any time you call toString , in debugging or otherwise, all side effects will occur. This is exactly why you should avoid

问题 In what format does ToStringBuilder.reflectionToString(Object) display dates? According to the Apache Commons Lang 2.4 documentation, ToStringBuilder.reflectionToString(Object) delegates to ReflectionToStringBuilder.toString(Object) which "Builds a toString value using the default ToStringStyle through reflection." So, in what format does the default ToStringStyle display dates? 回答1: DefaultToStringStyle is just an immutable subclass of ToStringStyle , so it falls back on that for handling.

问题 When javascript is run in the browser there is no need to try and hide function code because it is downloaded and viewable in source. When run on the server the situation changes. There are use cases such as api where you want to provide users with functions to call without allowing them to view the code that which is run. On our specific case we want to execute user submitted javascript inside node. We are able to sandbox node.js api however we would like to add our own api to this sandbox

问题 This is what I have so far. What this program basically does is take user input(their social security numbers), verifies that their input is in the proper format (XXX-XX-XXXX), adds the verified input to the arrays list. Now the final step is to create a toString() method that will return a human readable String representation of all social security numbers added to the array. This method must use a for loop, and must print 1 social security number entry per line. For example: "The Social

问题 I would like to create the following trait: trait IntSet[A] extends Traversable[A] { self: Product => def foreach[U](f: A => U): Unit } case class AProduct(a: List[Int], b: List[Int]) extends IntSet[Int] { def foreach[U](f: Int => U): Unit = { for(aa <- a; bb <- b) f(aa*bb) } } AProduct(List(1, 5,6,7), List(2,3,4,5)).toString returns (2, 3, 4, 5, 10, 15, 20, 25, 12, 18, 24, 30, 14, 21, 28, 35) But I don't want the toString method from the case class to be overriden by the one of the

问题 I cannot believe there is no smart way to get something like this from a 2D array, in this case int[,] a : "{1,2,3},{4,5,6},{7,8,9}" I have read many similar questions and learned that string.Join() can only be used on jagged arrays (in 2D). But I don't want to use them because of the more complex initialization and because it just feels bad when my rows, which all have the same length, are spread over several places in memory. This is my "normal" code: var s = ""; for (int i = 0; i < a
