[英]Best way get first word and rest of the words in a string in C#
In C# 在C#中
var parameters =
from line in parameterTextBox.Lines
select new {name = line.Split(' ').First(), value = line.Split(' ').Skip(1)};
Is there a way to do this without having to split twice? 有没有办法做到这一点,而不必分裂两次?
you can store the split in a let
clause 您可以将拆分存储在let
子句中
var parameters =
from line in parameterTextBox.Lines
let split = line.Split(' ')
select new {name = split.First(), value = split.Skip(1)};
Sure. 当然。
var parameters = from line in parameterTextBox.Lines
let words = line.Split(' ')
select new { name = words.First(), words.skip(1) };
string Str= "one all of the rest";
Match m = Regex.match(Str,"(\w*) (\w.*)");
string wordone = m.Groups[1];
string wordtwo = m.Groups[2];
You might try this: 你可以试试这个:
private Dictionary<string, string> getParameters(string[] lines)
{
Dictionary<string, string> results = new Dictionary<string, string>();
foreach (string line in lines)
{
string pName = line.Substring(0, line.IndexOf(' '));
string pVal = line.Substring(line.IndexOf(' ') + 1);
results.Add(pName, pVal);
}
return results;
}
