C# StreamReader的问题

好的，这是我到目前为止得到的

List<string> lines = new List<string>();

using (StreamReader r = new StreamReader(f))
{
    string line;
    while ((line = r.ReadLine()) != null)
    {
        lines.Add(line);
    }
}

foreach (string s in lines)
{
    NetworkStream stream = irc.GetStream();

    writer.WriteLine(USER);
    writer.Flush();
    writer.WriteLine("NICK " + NICK);
    writer.Flush();
    writer.WriteLine("JOIN " + s);
    writer.Flush();


    string trimmedString = string.Empty;


    CHANNEL = s;
}

这是向IRC写的唯一方法，那么有没有办法让“频道”只作为文本的开头，只是#lol，这样它就不会写密码了

我希望你能理解我的问题。

你可以在一个空格上拆分并拿走第一件物品：

CHANNEL = s.Split(' ')[0];

这将导致

{“#lol”，“test”}

，尽管理想情况下会事先检查：

string input = "#lol test";
string channel = "";
string key = "";
if (input.Contains(" "))
{   
    string[] split = input.Split(' ');
    channel = split[0];
    key = split[1];
}
else
{
    channel = input;
}
Console.WriteLine("Chan: {0}, Key: {1}", channel, key);

string input = "#lol test";
string channel = "";
string key = "";
if (input.Contains(" "))
{   
    string[] split = input.Split(' ');
    channel = split[0];
    key = split[1];
}
else
{
    channel = input;
}
Console.WriteLine("Chan: {0}, Key: {1}", channel, key);

CHANNEL = s.Substring(0,s.IndexOf(" "));
