.net 开发的奇淫巧计

随机数

Random random = new Random(( int)DateTime .Now.Ticks & 0x0000FFFF);

如何让ASP.NET Web API显示完整的错误信息，并显示错误堆栈？

在ASP.NET Web API项目的Application_Start中添加下面的代码：
GlobalConfiguration.Configuration.IncludeErrorDetailPolicy = IncludeErrorDetailPolicy.Always;

自动清除运行测试用例之后产生的 TestResults垃圾文件夹

在测试项目的配置文件的末尾里添加

<PropertyGroup>

    <TestResultsFolderPath>..TestResults</TestResultsFolderPath>

</PropertyGroup>

<Target Name="AfterClean">

    <RemoveDir Directories="$(TestResultsFolderPath)" Condition="Exists('$(TestResultsFolderPath)')" />

</Target>

或者用msbuild的命令

MSBuild /t:Clean MyProject.csproj

@的用法

1字符串换行

Regular literal	Verbatim literal	Resulting string
`"Hello"`	`@"Hello"`	`Hello`
`"Backslash: \"`	`@"Backslash: "`	`Backslash:`
`"Quote: ""`	`@"Quote: """`	`Quote: "`
`"CRLF: Post CRLF"`	`@"CRLF:` `Post CRLF"`	`CRLF:` `Post CRLF`

2用语言的保留关键字作为变量名(不是很建议这么做

× object object=null;

√ object @bject=null;

返回当前的方法签名

using System.Reflection;

 [Test]
        public void 返回当前方法名()
        {
            StackTrace st = new StackTrace();
            StackFrame sf = st.GetFrame(0);
            MethodBase currentMethodName = sf.GetMethod();
            Console.WriteLine(currentMethodName.ToString());
        }

//Void 返回当前方法名()

编辑器特性

生成构造函数

构造函数输入ctor 在按TAB键

public const int

public const string

public int property { get; private set; } propg

public static readonly

web.config

移除X-AspNet-Version HTTP头

在web.config里配置

    <!-- 移除X-AspNet-Version HTTP头 -->
    < httpRuntime targetFramework ="4.5 " enableVersionHeader ="false " />
