基于阵列的元素替换字符串 [英] Replace string based on array element
本文介绍了基于阵列的元素替换字符串的处理方法,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
我有一些价值数组,也有一些参数string.I双双下面放置。
我想,以取代基于阵列元件的参数字符串。请帮我做THI。
的String [] = arrayval {类型:1,行动:DOIT,消息:海};字符串参数=类型:类型] #Action:[动作] #Message:[信息] #OutMsg:[OutMsg]#@将RetVal:[将RetVal];我期望输出
字符串参数=类型:1#操作:DOIT#消息:海#OutMsg:[OutMsg]#@将RetVal:[将RetVal];
解决方案
不测试,应该增加一些检查,但看到@Ulugbek Umirov的版本:)
VAR模式= @\\ [(。*?)\\];
VAR匹配= Regex.Matches(参数,图案);的foreach(在比赛中赛米){
变种INB =[+ m.Groups [1] +];
VAR的结果= arrayval.Select(S = GT; s.Split(':'))
.FindAll(β= GT; SS [0] == m.Groups [1])
。选择(SS => SS [1]);
参数= Param.Replace(INB,结果[0]);
}
BTW ...有点短版@Ulugbek Umirov的应该只是正常工作:)
参数= Regex.Replace(参数,@\\ [。?(+)\\],M =>
arrayval.Select(S = GT; s.Split(新[] {':'},2))
。凡(p值=> p.Length == 2)
。凡(p值=指p [0] == m.Groups [1]。价值)
。选择(p值=指p [1])
.FirstOrDefault()? m.Value);
更新与更换0如果不存在:
参数= Regex.Replace(参数,@\\ [。?(+)\\],M =>
arrayval.Select(S = GT; s.Split(新[] {':'},2))
。凡(p值=> p.Length == 2)
。凡(p值=指p [0] == m.Groups [1]。价值)
。选择(p值=指p [1])
.FirstOrDefault()? 0);
I have a array with some value and also having some parameter string.I have placed both below. I would like to replace the parameter string based on array element. Please help me to do thi.
string[] arrayval = {"Type:1","Action:doit","Message:hai"};
string Param = "Type:[Type]#Action:[Action]#Message:[Message]#OutMsg:[OutMsg]#@RetVal:[RetVal]";
My Expected Output
string Param = "Type:1#Action:doit#Message:hai#OutMsg:[OutMsg]#@RetVal:[RetVal]";
解决方案
not tested and some checks should be added but, see in version of @Ulugbek Umirov :)
var pattern = @"\[(.*?)\]";
var matches = Regex.Matches(Param, pattern);
foreach (Match m in matches) {
var inb = "[" + m.Groups[1] + "]";
var results = arrayval.Select (s => s.Split(':'))
.FindAll(ss => ss[0] == m.Groups[1])
.Select (ss => ss[1]);
Param = Param.Replace(inb, results[0]);
}
btw... a bit shorter version of @Ulugbek Umirov which should work just fine :)
Param = Regex.Replace(Param, @"\[(.+?)\]", m =>
arrayval.Select(s => s.Split(new[] { ':' }, 2))
.Where (p => p.Length == 2)
.Where (p => p[0] == m.Groups[1].Value)
.Select(p => p[1])
.FirstOrDefault() ?? m.Value);
Update for replace with 0 if not exists:
Param = Regex.Replace(Param, @"\[(.+?)\]", m =>
arrayval.Select(s => s.Split(new[] { ':' }, 2))
.Where (p => p.Length == 2)
.Where (p => p[0] == m.Groups[1].Value)
.Select(p => p[1])
.FirstOrDefault() ?? "0");
