+C# 备忘清单
+===
+
+提供基本语法和方法的 C# 快速参考备忘单
+
+入门
+--------
+
+### Hello.cs
+
+```cs
+class Hello {
+ // main method
+ static void Main(string[] args)
+ {
+ // 输出: Hello, world!
+ Console.WriteLine("Hello, world!");
+ }
+}
+```
+
+编译运行（确保在项目目录下）
+
+```shell
+$ dotnet run
+Hello, world!
+```
+
+### 变量
+
+```cs
+int intNum = 9;
+long longNum = 9999999;
+float floatNum = 9.99F;
+double doubleNum = 99.999;
+decimal decimalNum = 99.9999M;
+char letter = 'D';
+bool @bool = true;
+string site = "quickref.me";
+var num = 999;
+var str = "999";
+var bo = false;
+```
+
+### 原始数据类型
+
+数据类型 | 尺寸 | 范围
+:- | - | -
+| `int` | 4 bytes | -2^31^ ^to^ 2^31^-1 |
+| `long` | 8 bytes | -2^63^ ^to^ 2^63^-1 |
+| `float` | 4 bytes | 6 ^to^ 7 decimal digits |
+| `double` | 8 bytes | 15 decimal digits |
+| `decimal` | 16 bytes | 28 ^to^ 29 decimal digits |
+| `char` | 2 bytes | 0 ^to^ 65535 |
+| `bool` | 1 bit | true / false |
+| `string` | 2 bytes per char | _N/A_ |
+
+
+### 注释
+
+```cs
+// 单行注释
+/* 多行
+ 注释 */
+// TODO：向 Visual Studio 中的任务列表添加注释
+/// 用于文档的单行注释
+/** 多行 注释
+ 用于文档 **/
+```
+
+### Strings
+
+```cs
+string first = "John";
+string last = "Doe";
+// 字符串连接
+string name = first + " " + last;
+Console.WriteLine(name); // => John Doe
+```
+
+查看: [Strings](#c-字符串)
+
+### User Input
+
+```cs
+Console.WriteLine("Enter number:");
+if(int.TryParse(Console.ReadLine(),out int input))
+{
+ // 输入验证
+ Console.WriteLine($"You entered {input}");
+}
+```
+
+
+### 条件句
+
+```cs
+int j = 10;
+if (j == 10) {
+ Console.WriteLine("I get printed");
+} else if (j > 10) {
+ Console.WriteLine("I don't");
+} else {
+ Console.WriteLine("I also don't");
+}
+```
+
+### 数组
+
+```cs
+char[] chars = new char[10];
+chars[0] = 'a';
+chars[1] = 'b';
+string[] letters = {"A", "B", "C"};
+int[] mylist = {100, 200};
+bool[] answers = {true, false};
+```
+
+### 循环
+
+```cs
+int[] numbers = {1, 2, 3, 4, 5};
+for(int i = 0; i < numbers.Length; i++) {
+ Console.WriteLine(numbers[i]);
+}
+```
+
+---
+
+```cs
+foreach(int num in numbers) {
+ Console.WriteLine(num);
+}
+```
+
+C# 字符串
+----------------
+
+### 字符串连接
+
+```cs
+string first = "John";
+string last = "Doe";
+string name = first + " " + last;
+Console.WriteLine(name); // => John Doe
+```
+
+### 字符串插值
+
+```cs
+string first = "John";
+string last = "Doe";
+string name = $"{first} {last}";
+Console.WriteLine(name); // => John Doe
+```
+
+### 字符串成员
+
+
+成员 | 说明
+:- | -
+`Length` | 返回字符串长度的属性
+`Compare()` | 比较两个字符串的静态方法
+`Contains()` | 确定字符串是否包含特定的子字符串
+`Equals()` | 确定两个字符串是否具有相同的字符数据
+`Format()` | 通过 {0} 表示法和使用其他原语格式化字符串
+`Trim()` | 从尾随和前导字符中删除特定字符的所有实例。 默认删除前导和尾随空格
+`Split()` | 删除提供的字符并从两侧的剩余字符中创建一个数组
+
+
+### 逐字字符串
+
+```cs
+string longString = @"I can type any characters in here !#@$%^&*()__+ '' \n \t except double quotes and I will be taken literally. I even work with multiple lines.";
+```
+
+
+### 成员示例
+
+```cs
+// 使用 System.String 的属性
+string lengthOfString = "How long?";
+lengthOfString.Length // => 9
+// 使用 System.String 的方法
+lengthOfString.Contains("How"); // => true
+```
+
+杂项
+-----------
+
+### 一般 .NET 条款
+
+
+条款 | 定义
+:- | -
+Runtime | 执行给定的已编译代码单元所需的服务集合
+Common Language Runtime (CLR) | 主要定位、加载和托管 .NET 对象。
CLR 还处理内存管理、应用程序托管、线程协调、执行安全检查和其他低级细节
+Managed code | 在 `.NET` 运行时编译和运行的代码。 C#/F#/VB 就是例子
+Unmanaged code | 直接编译为机器代码且不能由 .NET 运行时直接托管的代码。
不包含空闲内存管理、垃圾收集等。从 C/C++ 创建的 DLL 就是示例
