拆分字符串数组并作为字符串返回

问题描述

我的输入是:

My input is :

string[] sinput= { "1||age--11||gender--Female|||||", "0||age--16||gender--Male|||||" };

我需要循环输出，例如

I need output in loop such as

string soutput = ("age--11,age--16" );
string soutput = ("gender--Female,gender--Male" );

但是我已经尽力了，我无法实现此解决方案.

But I have tried myself, I couldn''t achieve this solution.

private void button8_Click(object sender, EventArgs e)
       {
           string[] ss = { "1||age--11||gender--Female|||||", "0||age--16||gender--Male|||||" };

           for (int i = 0; i < ss.Length; i++)
           {
               string sss = ss[i].ToString().Replace("||",",").Replace(",,","");
           }

       }

我尝试过的事情:

What I have tried:

private void button8_Click(object sender, EventArgs e)
       {
           string[] ss = { "1||age--11||gender--Female|||||", "0||age--16||gender--Male|||||" };

           for (int i = 0; i < ss.Length; i++)
           {
               string sss = ss[i].ToString().Replace("||",",").Replace(",,","");
           }

       }

推荐答案

string sss;
string[] ss = { "1||age--11||gender--Female|||||", "0||age--16||gender--Male|||||" };

string op1 = String.Empty;
string op2 = String.Empty;

for (int i = 0; i < ss.Length; i++)
{
     sss = ss[i].ToString().Replace("||",",").Replace(",,","");
     string[] p = sss.Split('','');
     op1 += String.Format("{0},", p[1]);//age details
     op2 += String.Format("{0},", p[2]);//gentder details
}

ss[0] = "1||age--11||gender--Female|||||";
ss[1] = "0||age--16||gender--Male|||||" ;

您可以在垂直条|上Split数组上的每个条目.如果确定数组中的每个项目都采用相同的格式，则可以使用StringSplitOptions.RemoveEmptyEntries选项.

如果要从这些项目中重建字符串，则应使用 [ ^ ]类

下面的代码假定数组ss中的每个项目与问题中显示的格式完全相同.

You can Split each entry on the array on the vertical bar |. If you are sure that every item in the array will be in that same format then you could use the StringSplitOptions.RemoveEmptyEntries option.

If you are going to reconstruct a string from these items then you should use the StringBuilder[^] class

The code below assumes that each of the items in the array ss is in exactly the same format as shown in your question

string[] ss = { "1||age--11||gender--Female|||||", "0||age--16||gender--Male|||||" };

StringBuilder sb1 = new StringBuilder("(");
StringBuilder sb2 = new StringBuilder("(");
for (int i = 0; i < ss.Length; i++)
{
    var s1 = ss[i].Split(new []{'|'}, StringSplitOptions.RemoveEmptyEntries);
    sb1.Append(s1[1]);
    if(i < ss.Length - 1) sb1.Append(",");
    sb2.Append(s1[2]);
    if (i < ss.Length - 1) sb2.Append(",");
}
sb1.Append(")");
sb2.Append(")");

Debug.Print(sb1.ToString());
Debug.Print(sb2.ToString());

或者，您可以搜索以"age"，"gender"开头的项目-例如:

Alternatively you can search for the item that begins with "age", "gender" - example:

foreach (var s in s1.Where(s => s.StartsWith("age")))
{
    sb1.Append(s);
    if (i < ss.Length - 1) sb1.Append(",");
}
