IntroductionNScript is a tool similar to WScript except that it allows scripts to be written in .NET languages such as C#, VB.NET and JScript.NET. NScript automatically compiles the code into an assembly in memory and executes the assembly. The
NOTE: The project name in this sample code is mcWebService which is a spelling mistake. I meant to put mcWinService. And now I don't want to change all the screen shots and code all over again. I hope it won't confuse you :). Ok, its time for one
例如有這樣一個string類型的數組:{ "A", "B", "C", "B", "A", "B", "C", "B" },求這個集合內相同元素的個數?C#解法:(1)通過linq解答: string arr={ "A", "B", "C", "B", "A", "B", "C", "B" }; var result = from s in arr group s by s; foreach (var s in result) {
