一个字符连接问题

[arthurzhujie]

我想用split把一个句子中所有的词提取出来。
string [] finalstr=null;

sec="I am a student";
char [] k=new char[1] ;


k[0]=(char)20;
finalstr=sec.Split(k,0);
string kong="";
foreach (string s in finalstr)
{
kong=kong+s;
}
button5.Text=kong.ToString();


结果不正确。请高手指教。我想要的结果是Iamastudent

[diandian82]

using System;
public class MyClass
{
public static void Main()
{
string sec="I am a student";
string kong = sec.Replace(" ", "");
Console.WriteLine("kong 的值为 {0}", kong);

Console.ReadLine();
}

}

楼上都可以。。。。用Replace方法就ok了

[YYKXQ]

string str="I am a student";
string [] s=str.Split(' ');
string result="";
foreach(string s1 in s)
{
if(s1.Trim()!="")
result+=s1;
}
MessageBox.Show(result);

用Replace直接过滤空格不是更简单么？

[seraphgxh]

k[0]=(char)20; -> k[0]=(char)0x20;
sec.Split(k,0); -> sec.Split(k);

using System.Text.RegularExpressions;

public class MyClass
{
public static void Main()
{
string [] finalstr = null;
string sec="I am a student";

Regex r = new Regex("\\s+");

finalstr = r.Split(sec);
string kong = "";
for(int i=0;i<finalstr.Length;i++)
{
Console.WriteLine("finalstr[{0}]={1}", i, finalstr[i]);
kong=kong + finalstr[i];
}
Console.WriteLine("kong 的值为 {0}", kong);

Console.ReadLine();
}
