阅读更多关于 Read from App.config in a Class Library project

问题 I am developing a simple class library project, which will give me a dll. I wanted a particular value to be read from a config file. So I have added an App.config file to my project. <?xml version="1.0" encoding="utf-8" ?> <configuration> <appSettings> <add key="serviceUrl" value="test value" /> </appSettings> </configuration> Above is my App.config file, and now I am trying to read it as following string strVal = System.Configuration.ConfigurationManager.AppSettings["serviceUrl"]; But I am

Java Array sort: Quick way to get a sorted list of indices of an array

阅读更多关于 Java Array sort: Quick way to get a sorted list of indices of an array

问题 The problem: Consider the following floats[]: d[i] = 1.7 -0.3 2.1 0.5 What I want is an array of int[] that represents the order of the original array with indices. s[i] = 1 3 0 2 d[s[i]] = -0.3 0.5 1.7 2.1 Of course it could be done with a custom comparator, a sorted set of custom objects, or by simply sorting the array and then searching for the indices in the original array (shudder). What I am in fact looking for is the equivalent for the second return argument of Matlab's sort function.

阅读更多关于 app.config for a class library

I cannot see a app.config file generated for a class library by the VS2008 wizard. In my research I found that in an application only one app.config exists. Is it a bad thing to add an app.config manually to a class library or are there any other methods which will serve the purpose of an app.config in class library? I need to store log4net config information inside the app.config file. You generally should not add an app.config file to a class library project; it won't be used without some painful bending and twisting on your part. It doesn't hurt the library project at all - it just won't do

阅读更多关于 What is the difference between a class library and a framework

问题 I hear the whole day the terms class library, base class library, Framework, ... What highlights a framework and what a base class library? 回答1: The distinguishing feature between a class library and a software framework is that in a framework, the flow of control is not determined by the user´s code, but by the framework. This is also known as Hollywood principle (don´t call us, we call you). By the way, there is also a nice Wikipedia article on this topic. 回答2: You use a class library in

How can I use external JARs in an Android project?

阅读更多关于 How can I use external JARs in an Android project?

问题 I have created an Android project and added an external JAR (hessian-4.0.1.jar) to my project. I then added the JAR to the build path and checked it off in Order and Export. Order and Export is ignored it seems, and all classes from the external JAR are missing at runtime. Is there a trick to properly include the needed classes from an external JAR when building an Android application using the Eclipse plugin? I do not want to use ant or Maven. 回答1: For Eclipse A good way to add external JARs
