将字符串拆分为字符串数组。

本文介绍了将字符串拆分为字符串数组。的处理方法，对大家解决问题具有一定的参考价值，需要的朋友们下面随着小编来一起学习吧！ 问题描述

我在C＃中执行sql查询时遇到问题。当字符串在IN CLAUSE中包含超过1000个enteries时，sql查询会抛出错误。该字符串有超过1000个子字符串，每个子字符串由''，'分隔。 我想将字符串拆分成字符串数组，每个字符串包含999个字符串，分别用''，''。 或 如何在字符串中找到''，''的第n个出现。

解决方案

看看String.Split

string foo = a，b，c; string [] foos = foo.Split（ new char [] {' ，'}）; foreach （ var item in foos） { Console.WriteLine（item）; }

你可以在C＃中快速完成这些。 只需使用字符串.split 功能。 这样的东西可行 - strArry = myString.split（@，） ;

在C＃中，只需使用.Split

string STR = abc，def，ghi，jkl， MNO，PQR; string [] phrase = STR.Split（' ）; string nthPhrase = phrase [n];

或者，您可以使用RegEx获取数字如下

字符串 s = abc，def，ghi，jkl，mno，pqr; int n = 3 ; int j = -1; MatchCollection myMatches = Regex.Matches（s， ，）; 如果（myMatches.Count > = n-1） {j = myMatches [n - 1 ]。索引; }

I am facing a problem while executing a sql query in C#.The sql query throws an error when the string contains more than 1000 enteries in the IN CLAUSE .The string has more than 1000 substrings each seperated by '',''. I want to split the string into string array each containing 999 strings seperated by '',''. or How can i find the nth occurence of '','' in a string.

解决方案

Take a look at String.Split

string foo = "a,b,c"; string [] foos = foo.Split(new char [] {','}); foreach(var item in foos) { Console.WriteLine(item); }

You can do these very quickly in C#. Just use the string.split function. Something like this would work - strArry = myString.split(@",");

In C#, simply use .Split

string STR = "abc,def,ghi,jkl,mno,pqr"; string[] phrases = STR.Split(','); string nthPhrase = phrases[n];

Alternatively, you can use RegEx to get the number as below

String s = "abc,def,ghi,jkl,mno,pqr"; int n = 3; int j=-1; MatchCollection myMatches = Regex.Matches(s, ","); if (myMatches.Count >= n-1 ) { j = myMatches[n - 1].Index; }
