我这里写了个String扩展类,模仿原生的Split方法,与原生Split方法的区别在于多了个返回分隔符的枚举功能。 classProgram{staticvoidMain(string[] args){varflagEx = StringSplitOptionsEx.RemoveEmptyEntries | StringSplitOptionsEx.ReturnSepapator | StringSplitOptionsEx.TrimEntries;varresult =" A | B | |C|D".Spli...
Here is an example of how you can use the Split method in C# to split the string "You win some. You lose some." using space and period as delimiters: using System; class Program { static void Main() { string input = "You win some. You lose some."; char[] delimiters = new char...
