I have string str = "Join Smith hate meat"
.
I want to get JoinSmith
from this str
.
I tried code:
private static string GetFirstWord(string str)
{
return str.Split(' ').Take(2).ToString();
}
This code not working for me.
I tried: return str.Split(' ').FirstOrDefault
it get only first part of string Join
.
采用
string result = string.Concat(str.Split(' ').Take(2)); // "JoinSmith"
A Fancy combination:
var result = string.Join(String.Empty, str.Split(' ').Take(2));
Takes the first two words, joins them into one string.
Or:
var result = string.Concat(str.Split(' ').Take(2));
Something a little different
var result = new string(TakeAllUntilSecondSpace(str).ToArray());
Yield the characters you want... sometimes this is a good way if you need a lot of control that standard methods don't provide.
private IEnumerable<char> TakeAllUntilSecondSpace(string s)
{
var spaceEncountered = false;
foreach (char c in s)
{
if (c == ' ')
{
if (spaceEncountered) yield break;
spaceEncountered = true;
} else yield return c;
}
}
