根据数组元素替换字符串

Question

我有一个数组，有一些值，也有一些参数字符串。我把两者都放在下面。我想替换基于数组元素的参数字符串。请帮我做这件事。

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]";

Answer 1

未经过测试，应该添加一些检查，但是，参见@Ulugbek Umirov版本:)

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]);
}

顺便说一句……@Ulugbek Umirov的简短版本，应该可以正常工作:)

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);

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");

不太整洁。但是根据你提供的信息。

string[] arrayval = { "Type:1", "Action:doit", "Message:hai" };
string Param = string.Format("Type:{0}#Action:{1}#Message:{2}", arrayval[0].Split(':')[1], arrayval[1].Split(':')[1], arrayval[2].Split(':')[1]);

输出:

类型:1 #行动:doit #消息:海

略作修改的@Heather

Param = Regex.Replace(Param, @"[(.+?)]", m =>
{
    string paramName = m.Groups[1].Value;
    string paramValue = arrayval.Select(s => s.Split(new[] { ':' }, 2))
                                .Where(p => p.Length == 2)
                                .Where(p => p[0] == paramName)
                                .Select(p => p[1])
                                .FirstOrDefault();
    return paramValue ?? m.Value;
});

试试下面的代码，我已经在VS 2012中测试过了

string[] arrayval = { "Type:1", "Action:doit", "Message:hai" };
string Param = "Type: " + arrayval[0].Split(Convert.ToChar(":"))[1] + "#Action: " + arrayval[1].Split(Convert.ToChar(":"))[1] + "#Message: " + arrayval[2].Split(Convert.ToChar(":"))[1];

输出

: -

Type: 1#Action: doit#Message: hai
