Answer 1

                    System.IO.File.WriteAllLines(string path,string[]Data)

Answer 2

        using (StreamWriter sw = File.AppendText(path)) 
        {
            sw.WriteLine("10.100.182.89");
            sw.WriteLine("10.100.182.90 ");
        }

Answer 3

StreamWriter writer = new StreamWriter(filepath);
writer.Write(string.Concat("10.100.182.89",Environment.NewLine));
writer.Write(string.Concat("10.100.182.90",Environment.NewLine));
writer.Close();

Answer 4

StreamWriter my_writer = null;
string txtstr="10.100.182.89\r\n10.100.182.90"
my_writer = new StreamWriter(@"d:\abc.txt", true, System.Text.Encoding.Default);
my_writer.Write(txtstr);
my_writer.Flush();

Answer 5

        System.IO.StreamWriter fs = new System.IO.StreamWriter("C:\aa.txt")
        fs.WriteLine("10.100.182.89");
        fs.WriteLine("10.100.182.90");fs.flush();

Answer 6

static void Main(string[] args)
{
    string[] strs = new string[]
    {
        "10.100.182.89",
        "10.100.182.90"
    };
    using (FileStream fileStream = File.OpenWrite("C:\\test.txt"))
    {
        using (StreamWriter writer = new StreamWriter(fileStream))
        {
            foreach (string s in strs)
            {
                writer.WriteLine(s);
            }
            writer.Close();
        }
    }
}

Answer 7

直接用StreamWriter更方便，上面我绕弯了。static void Main(string[] args)
{
    string[] strs = new string[]
    {
        "10.100.182.89",
        "10.100.182.90"
    };    using (StreamWriter writer = new StreamWriter("C:\\test.txt"))
    {
        foreach (string s in strs)
        {
            writer.WriteLine(s);
        }
        writer.Close();
    }
}

Answer 8

string[] s={"10.100.182.89","10.100.182.90"};
StreamWriter swFromFile = new StreamWriter(logFile);
for(int i=0;i<s.Length;++i)
swFromFile.WriteLine(s[i]);
swFromFile.Close();

Answer 9

 using (StreamWriter sw = File.AppendText(path)) 
        { 
            sw.WriteLine("10.100.182.89"); 
            sw.WriteLine("10.100.182.90 "); 
        }
