如何将键/值添加到字典c＃ [英] How to add Key/Value to dictionary c#

问题描述

我有一个字符串Abc = {GRFD_Id = 29，GL_Id = 1，CK_Id = 15，CPM_Current_Float = 405012.1700，CGJM_Allowed_Float = 99999999.0000，WL_Name = RahnamCP，PK_Amount = 750.00，GK_Name = Domestic Diamond， GP_PK_Id = 51，VG_Expiry = 365，CP_Name = JohnClient}



来自字符串的样本



in GRFD_Id = 29

GRFD_Id是钥匙

29是价值



现在我也想要键和值进入字典..我怎么能实现这个目的！

解决方案

一个非常强力的解决方案可能是使用字符串。拆分方法。类似于：

  foreach （ string 元素 in  originalstring.Split（' ，'））{
 myDictionary.Add（element.Split（'  ='）[< span class =code-digit> 0 ]，element.Split（'  ='）[ 1 ]）; 
} 

您可能：

• 删除标题和尾随花括号。
• 迭代通过使用'，'字符作为分隔符拆分剩余字符串而获得的数组。
• 将数组添加到字典中获得的项目再次拆分该项目，这次使用'='字符作为分隔符。

  string  Abc =   GRFD_Id = 29，GL_Id = 1，CK_Id = 15，CPM_Current_Float = 405012.1700，CGJM_Allowed_Float = 99999999.0000，WL_Name = RahnamCP，PK_Amount = 750.00，GK_Name =国内钻石，GP_PK_Id = 51，VG_Expiry = 365，CP_Name = JohnClient; 
 
  //  如果您只想将字符串转换为Dictionary，那么您可以关注代码。  
 
  var  Dictionary = Abc.Split（&＃39;，&＃39;）。ToList（）。选择（m =& gt; 
 {
  var  res = m.Split（&＃39; =&＃39;） ; 
 Dictionary& lt;  string ，string& gt; dict =  new  Dictionary& lt;  string ，string& gt;（）; 
 dict.Add（res [ 0 ]， res [ 1 ]）; 
  return  dict; 
}）; 
 
  //  如果想要将字符串的第一个值转换为字典，那么你可以以下代码。 
 
  var  FirstRecord = Abc.Split（&＃39;，&＃39;）。ToList （）。选择（m =& gt; 
 {
  var  res = m.Split（&＃39; =&＃ 39;）; 
字典& lt; 字符串，字符串& gt; dict = 新字典& ; lt;  string ，string& gt;（）; 
 dict.Add（res [ 0 ]，res [ 1 ]）; 
  return  dict; 
}） .FirstOrDefault（）; < /   pre  > < /跨度> 

i have a string Abc = {GRFD_Id=29, GL_Id=1, CK_Id=15, CPM_Current_Float=405012.1700, CGJM_Allowed_Float=99999999.0000, WL_Name=RahnamCP, PK_Amount=750.00, GK_Name=Domestic Diamond, GP_PK_Id=51, VG_Expiry=365, CP_Name=JohnClient}

Sample from string

in GRFD_Id=29
GRFD_Id is the Key
29 is Value

now i want too the keys and values into dictionary .. how can i achieve this!

解决方案

A very brute force solution could be to use string.Split method. Something like:

foreach (string element in originalstring.Split(',')) {
   myDictionary.Add(element.Split('=')[0], element.Split('=')[1]);
}

You might:

• remove the heading and trailing curly braces.
• iterate over the array obtained by splitting the remaining string using the ',' character as separator.
• add to the dictionary the array items obtained splitting again the item, this time using the '=' character as separator.

string Abc = "GRFD_Id=29, GL_Id=1, CK_Id=15, CPM_Current_Float=405012.1700, CGJM_Allowed_Float=99999999.0000, WL_Name=RahnamCP, PK_Amount=750.00, GK_Name=Domestic Diamond, GP_PK_Id=51, VG_Expiry=365, CP_Name=JohnClient";

//IF you simply want the string to converted into Dictionary then you can  following code.

            var Dictionary = Abc.Split(',').ToList().Select(m =>
            {
                var res = m.Split('=');
                Dictionary<string, string> dict = new Dictionary<string, string>();
                dict.Add(res[0], res[1]);
                return dict;
            });

//and if want the first values of  string to  be converted into Dictionary then you can  following code.

            var FirstRecord = Abc.Split(',').ToList().Select(m =>
            {
                var res = m.Split('=');
                Dictionary<string, string> dict = new Dictionary<string, string>();
                dict.Add(res[0], res[1]);
                return dict;
            }).FirstOrDefault();</pre>
