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");
