Python C语言中的拼接字符串#

如何在C#中拼接字符串？如何将以下python代码翻译成C#

---

我理解跨语言是很难的，因为有些东西不容易用谷歌搜索。尝试寻找“Python到C#cheatsheet”

C#8现在提供了与Python的切片表示法类似的简洁语法

string myString = "this is a string";

myString[^1]         // last letter
myString[..2]        // first 2 letters
myString[2..]        // letters after 2nd letter
myString[^2]         // second to last letter 
myString[^2..]       // last 2 letters

var words = myString.Split();                // list of words 
var string_again = string.Join(" ", words);  // list of words back to string

请解释一下你试过什么。因此不是代码翻译服务首先，不能在C#中使用变量名“string”。它是受保护的。通过简单地检查

System.String

，一些答案变得显而易见。对于其余部分，请查看

System.Linq.Enumerable

提供的扩展方法。但是，您不会得到Python提供的紧凑语法。

//py
string = "this is a string"
//c#
string myStringName = "this is a string";
var myStringName = "this is a string";
String myStringName = "this is a string"

//py
string[-1]          ## last letter
//c#
char c = myStringName[myStringName.Length-1];

//py
string[:2]           ## first 2 letters
//c#
string firstTwo = myStringName.Remove(2);

//py
string[2:]           ## letters after 2nd letter
//c#
string remainder = myStringName.Substring(2);

//py
string[-2]            ## last 2 letters
//c#
string lastTwo = myStringName.Substring(mystringName.Length - 2);

//py
words = string.split()    ## list of words 
//c#
myStringName = "this,is,a,string";
string[] strArray = myStringName.Split(',');

//py
string_again = "".join(words)  ## list of words back to 
//c#
string stringWithCommasAgain = string.Join(",", strArray);

string myString = "this is a string";

myString[^1]         // last letter
myString[..2]        // first 2 letters
myString[2..]        // letters after 2nd letter
myString[^2]         // second to last letter 
myString[^2..]       // last 2 letters

var words = myString.Split();                // list of words 
var string_again = string.Join(" ", words);  // list of words back to string
