這個一個google主持的開源項目，http://code.google.com/p/googletest/ gtest在google的很多其他的開源項目中都使用到了，如:chromium gtest的優點，就是寫案例簡單，並且跨平台，有一定的可擴充性 用TEST這個宏加上我們的代碼就可以生產一個案例，例如： TEST(FactorialTest, Zero) { EXPECT_EQ(1, Factorial(0)); } 在這裡FactorialTest是案例名稱, Zero是測試名稱

1. Class is reference type while Struct is value type.2. Referece type data will be allocated on the heap always, while value type data will be either on the stack as local variable for example or on the heap.3. Referece type holds a reference to

1. Why need it?Mainly it works as the bridge between managed code and native c++ code, as it's the only graceful way to be able to talk to both sides.Using /cli compiler option, it can generate mixed code to benefit below

1. Place your cursor, by a single click, immediately after the closing curly brace of theMain method. This highlights the beginning and closing braces.2. Press Ctrl+Enter. This inserts a new line between the curly braces, moves the cursor tothat

In C#, you have four types of method parameters: value, ref, out, and params.1. The default parameter type is value.2. If you want calling code to see changes to a value type variable, the parameter type should be ref. Ref parameters definitely must

 The syntax for stack versus heap allocation of C++, C++/CLI and CSharpNative C++ lets you choose where to create a given object.Any type can be allocated on the stack or the CRT heap.// allocated on the stackstd::wstring stackObject; // allocated

Snippet is so convenient to use in C#!I need to get the way / list of getting snippets in C# later on really!Now give a good example of using snippet to write switch:enum Months { Jan, Feb, Mar, Apr, May, Jun, Jul, Aug, Sep, Oct, Nov, Dec }Months

The pattern of properties encapsulating a single field is so common that C# 3.0 introduced auto-implemented properties. Here’s an example:public int Rating { get; set; }This Rating property encapsulates some value of type int. Because calling code

Using StatementThe using statement obtains one or more resources, executes a statement, and then disposes of the resource. A using statement is translated into three parts:acquisition, usage, and disposal.Example:using (Font font1 = new Font("Arial",

In C#, content regards with string includes:1. String typeIts features:　　a. built-in reference type.　　b. immutable (meaning that a string can’t be modified once created) and sealed (meaning that it can’t be derived from).　　c. string equality

因為新項目將主要用到CSharp，並同時會涉及Mix programming的問題，與Native C++ and C++ CLI (common language infrastructure)，今天迅速的google下，做些初步瞭解先。現在的理解：1. 這裡說的mix programming的意思應該是：讓CSharp的module，Native C++ module和C++ CLI的module之間可以互相調用。當然不是把這不同語言的code直接寫在一起嘍。。2.

To know the future of C#, look at The Future of C#To know the future of programming, look at Microsoft Perspectives on the Future of Programming有一點小小的認識：從C#的版本發展來看，每個版本都增加了新特性。增加的新特性大體上是為了：C#1.0, 2.0：集中精力汲取Java，c++這些流行靜態語言的精髓，打造最佳模仿吧；C# 3.0：引入了很多文法糖-

摘自： 如何快速定位一個函數的返回點如何快速定位一個函數的返回點，這對於一個比較短小精悍的函數來講，從來就不是問題，但是假設我們有一個名為LongFunction的1000行長的函數, 調用如下： 1bool bSuccess =

文章目錄 C# has used duck typing for a long time 1. Duck Typing ("If it walks like a duck and quacks like a duck, it must be a duck.") [Refer to here]Duck typing allows an object to be passed in to a method that expects a

1. Can I use typedefs in C#?No, C# has no direct equivalent of the C++ typedef. C# does allow an alias to be specified via the using keyword: using IntList = System.Collections.Generic.List<int>;but the alias only applies in the file in which

From this article in codeproject. Mixed mode programming is the absolute power of C++/CLI, and so is C++/CLI the superior and mightiest of all programming languages. C++/CLI is to C++, as it is to C. You can do C programming in C++. In the same

List<Employee> or EmployeeList?In current versions of C#, to get a strongly-typed collection, you need to define a separate type for that collection. So if you want to expose a collection of employees, you created an EmployeeCollection
