[英]convert comma separated string to list using linq
I have 3 comma separated strings FirstName, MiddleInitial, LastName
我有3个逗号分隔的字符串
FirstName, MiddleInitial, LastName
I have a class NameDetails
: 我有一个
NameDetails
类:
public class NameDetails
{
public string FirstName { get; set; }
public string MiddleInitial { get; set; }
public string LastName { get; set; }
}
I have the values for strings as: 我有字符串的值为:
FirstName ="John1, John2, John3"
MiddleInitial = "K1, K2, K3"
LastName = "Kenndey1, Kenndey2, Kenndey3"
I need to fill the NameDetails List with the values from the comma separated strings. 我需要用逗号分隔的字符串中的值填充NameDetails列表。
Any linq for this? 任何linq为此? I need this for my asp.net mvc (C#) application.
我需要这个用于我的asp.net mvc(C#)应用程序。
I don't neccesarily advocate this as a good solution but it does what you asked, which is to 'do it in LINQ'. 我不一定提倡这是一个很好的解决方案,但它会按照你的要求做,即“在LINQ中做”。
It is also probably not the most efficient solution. 它也可能不是最有效的解决方案。
string FirstName ="John1, John2, John3";
string MiddleInitial = "K1, K2, K3";
string LastName = "Kenndey1, Kenndey2, Kenndey3";
List<String> fn = new List<String>(FirstName.Split(','));
List<String> mi = new List<String>(MiddleInitial.Split(','));
List<String> ln = new List<String>(LastName.Split(','));
IEnumerable<NameDetails> result = from f in fn
join i in mi on fn.IndexOf(f) equals mi.IndexOf(i)
join l in ln on fn.IndexOf(f) equals ln.IndexOf(l)
select new NameDetails {f, i, l};
I used LINQPad to try this out first (with an anonymous class, not the NameDetails calss). 我首先使用LINQPad来尝试这个(使用匿名类,而不是NameDetails calss)。
您可以使用Linq to CSV库。
Further to my previous answer you could also try: 继我之前的回答,您还可以尝试:
// some setup
string firstName ="John1, John2, John3";
string middleInitial = "K1, K2, K3";
string lastName = "Kenndey1, Kenndey2, Kenndey3";
var fn = firstName.Split(',');
var mi = middleInitial.Split(',');
var ln = lastName.Split(',');
// the important bit
var s = fn.Select((f, index) => new NameDetails {f, i = mi[index], l = ln[index]});
It will be fragile to the string arrays having unequal numbers of entries. 具有不等条目数的字符串数组将是脆弱的。
