当我使用子字符串时，我一直在努力解决我的问题。

C＃ ： 

string sInput = "vegetable lasgane { receipt: cheese sauce etc...}";

我想要什么：

  • 使用子字符串删除“{”、“receipt:”和“}”
  • 然后将 sInput 分解为新的两个变量，例如：

从 ：

string sInput = "vegetable lasgane { receipt: cheese sauce etc...}";

至：

string sMeal = "vegetable lasgane";
string sReceipt= "cheese sauce etc...";

如何在 C# 中做到这一点？您的代码示例将非常受欢迎。谢谢！！

string sInput = "vegetable lasgane { receipt: cheese sauce etc...}";
string[] splitString = sInput.Split('{');
string firstString = splitString[0];
string secondString = splitString[1].Replace("}", "").Split(':')[1];

应该可以解决问题。

只需使用String.SubString和String.IndexOf这样的方法；

string sInput = "vegetable lasgane { receipt: cheese sauce etc...}";
string sMeal = sInput.Substring(0, sInput.IndexOf('{'));
Console.WriteLine(sMeal);
//vegetable lasgane 

string sReceipt = sInput.Replace('{', ' ').Replace('}', ' ');
sReceipt = sReceipt.Substring(sReceipt.IndexOf(':') + 1).Trim();
Console.WriteLine(sReceipt); 
//cheese sauce etc...

这里有一个DEMO。

您可以Replace()删除字符并Split("{")分隔 2 个字符串

string sInput = "vegetable lasgane { receipt: cheese sauce etc...}";
sInput = sInput.Replace("}", "");
sInput = sInput.Replace("receipt:", "");
string[] Parts = sInput.Split('{');

现在也许Trim()如果需要

string sMeal = Parts[0].Trim();
string sReceipt= Parts[1];

尝试value.split("{");

这并不难：

sMeal = sInput.Split(" { receipt: ")[0];

和

sReceipt = sInput.Split(" { receipt: ")[1];
sReceipt = sReceipt.Substring(0,sReceipt.Length-1);

string sInput = "vegetable lasgane { receipt: cheese sauce etc...}";
string one = sInput.Substring(0, sInput.IndexOf("{"));

int start = sInput.IndexOf("{");
int end = sInput.IndexOf("}");
string two = sInput.Substring(start + 1, end - start - 1);

Response.Write(one + "\n"); // your 1st requirement
Response.Write(two + "\n"); // your 2nd requirement
