Question

我需要使用JSON将此字符串序列化为多维数组。你会怎么做？

{FRMB [0] [的CssClass] = textarea的＆安培; [0] [必需] FRMB =真安培; [0] [值] =对＆安培FRMB; FRMB [1] [的CssClass] =广播安培; FRMB [1] [需要] =真安培; FRMB [1] [标题] = RDO＆安培; FRMB [1] [值] [2] [值] =一个＆安培; FRMB [1] [值] [2] [基线] =真安培; FRMB [1] [值] [3] [值] = 2＆安培; FRMB [1] [值] [3] [基线] =假安培; FRMB [2] [的CssClass] = INPUT_TEXT＆安培; FRMB [2] [必需] =假安培; FRMB [ 2] [值] =文本＆安培; FRMB [3] [的CssClass] =复选框＆安培; FRMB [3] [需要] =真安培; FRMB [3] [标题] = CHK＆安培; FRMB [3] [值] [2] [值] = CHK + 1和; FRMB [3] [值] [2] [基线] =真安培; FRMB [3] [值] [3] [值] = CHK + 2及FRMB [3] [值] [3] [基线] =假安培; FRMB [4] [的CssClass] =选择＆安培; FRMB [4] [需要] =假安培; FRMB [4] [多] =真＆安培; FRMB [4] [标题] = SEL＆安培; FRMB [4] [值] [2] [值] = SEL1＆安培; FRMB [4] [值] [2] [基线] =真安培; FRMB [4] [值] [3] [值] = SEL2＆安培; FRMB [4] [值] [3] [基线] =假安培; form_id =未定义}

修改多维度真的让我无法将这个字符串转换为JSON。我试图剥离括号以获得数组的索引列表，但是以有用的方式重建数组一直是最大的挑战。

所以我一直在做：

private static List<string> StripBrackets(string input)
        {
            var ret = new List<string>();
            var indx = 0;
            do
            {
                input = input.TrimStart('[');
                indx = input.IndexOf(']');
                if(indx !=-1)
                {
                    var newVal = input.Substring(0, indx);
                    ret.Add(newVal);
                    input = input.Remove(0, indx+1);
                }
            } while (indx != -1);

                //-- this is where I bonked
                string[,] results = new string[ret.Count, 23];    
                foreach (var r in ret)
                {                    
                }    
                 return ret;
            }

我一直在研究这个问题 - 因此疲惫/有限的问题。它开始觉得我这样做是“艰难的”，并想看看是否有人开悟有更好的想法。 TIA

扩展@ ratchetfreak的评论：

var str = "{frmb...";

//sanitize string
str = str.substring(1, str.length-1); //remove braces
str = str.replace(/\[([a-z]+)\]/gi, '["$1"]'); //enclose non-numeric keys in double quotes
str = str.replace(/=([^&]+)/g, '="$1"'); //enclose values in double quotes
str = str.replace(/"(true|false)"/g, "$1"); //remove double quotes around boolean values
str = str.replace(/&/g, ";"); //replace all ampersands with semi-colons

//initialize "frmb"
var frmb = [];
for (var i = 0; i < 5 /* a guess as to how long "frmb" will be */; i++){
  var values = [];
  for (var j = 0; j < 5 /* a guess as to how long each "values" field will be */; j++){
    values.push({});
  }
  frmb.push({values:values});
}

//evaluate as Javascript
eval(str);

//marshal to string
var result = JSON.stringify(frmb);

使这个解决方案难以实现通用的部分是你需要初始化“frmb”。例如，如果没有先将frmb[0].cssClass初始化为数组，然后使用frmb将对象添加到该数组，则无法调用push()。因此，您需要估计您认为frmb的大小，以及每个values子阵列的大小。

你如何将这个字符串转换为JSON？
