我想检查删除;
拆分的字符串中的副本,但我不知道下一步怎么办
我的代码是这样的:
string str = "PORTION G ON GROUND FLOOR;/n/nPORTION G ON GROUND FLOOR;/n/nabcdef1234;/n/nabcdef1234";
List<string> unitList = new List<string>();
foreach (string s in str.Replace("/n","").Split(';'))
{
unitList.Add(s);
}
if ((unitList.Distinct()).Count() == 1)
Label1.Text=unitList.FirstOrDefault();
else
{
//return more than 1 ,remove duplicate
//replace duplicate by "-" or ""
}
我的输出想要:"PORTION G ON GROUND FLOOR;/n/n-;/n/nabcdef1234;/n/n-"
。
我发现如果我使用string []数组而不是List,返回(unitList.Distinct()).Count()
是2而不是1,我想知道是否有错。
这是我的代码:
string str = "PORTION G ON GROUND FLOOR;/n/nPORTION G ON GROUND FLOOR;/n/nPORTION G ON GROUND FLOOR";
string[] unitList = new string[10];
int i=0;
foreach (string s in str.Replace("/n","").Split(';'))
{
unitList[i]=s;
i++;
}
我很高兴并感谢任何人帮助我解决它!
答案 0 :(得分:1)
string str = "PORTION G ON GROUND FLOOR;/n/nPORTION G ON GROUND FLOOR;/n/nabcdef1234;/n/nabcdef1234";
var list = str.Replace("/n", "").Split(';');
var result = (from s in list
group s by s
into g
select g.First()).ToList();
分割后,您可以按照数组中的字符串进行分组,然后选择第一个字符串。
答案 1 :(得分:1)
这是解决您问题的方法:
string str = "PORTION G ON GROUND FLOOR;/n/nPORTION G ON GROUND FLOOR;/n/nabcdef1234;/n/nabcdef1234";
List<string> selected=new List<string>();
var result = str.Split(';').Select(s =>
{
var word = s.Replace("/n", "");
if (selected.Contains(word))
{
return s.Replace(word,"")+"-";
}
else
{
selected.Add(word);
return s;
}
}).Aggregate<string, string>(null, (current, item) => current + item);
此代码返回您期望的字符串。
但是如果你想要没有重复的单词列表,这是获得它的另一种方法:
var list = str.Split(';').ToLookup(s => s.Replace("/n", "")).Select(e=>e.Key);
答案 2 :(得分:0)
string str = "PORTION G ON GROUND FLOOR;/n/nPORTION G ON GROUND FLOOR;/n/nabcdef1234;/n/nabcdef1234";
var temp = str.Replace("/n", string.Empty).Split(';').Distinct();
var result = string.Join("/n", temp);
