在 C# 中创建文件 (.htm)

我想知道使用 C# 创建简单 html 文件的最佳方法。

它使用类似 System.IO.File.Create 的东西吗？

像这样的东西——

using (FileStream fs = new FileStream("test.htm", FileMode.Create)) 
{ 
    using (StreamWriter w = new StreamWriter(fs, Encoding.UTF8)) 
    { 
        w.WriteLine("<H1>Hello</H1>"); 
    } 
}

Something like -

using (FileStream fs = new FileStream("test.htm", FileMode.Create)) 
{ 
    using (StreamWriter w = new StreamWriter(fs, Encoding.UTF8)) 
    { 
        w.WriteLine("<H1>Hello</H1>"); 
    } 
}

我会说 File.WriteAllText 是一种愚蠢的方法为 C# >= 3.5 编写一个文本文件。

File.WriteAllText("myfile.htm", @"<html><body>Hello World</body></html>");

我什至会说 File.WriteAllLines 足够愚蠢编写更大的 html，而无需过多地处理字符串组合。但“好”版本仅适用于 C# 4.0（稍差的版本是 C# >= 2.0）

List<string> lines = new List<string>();
lines.Add("<html>");
lines.Add("<body>");
lines.Add("Hello World");
lines.Add("</body>");
lines.Add("</html>");

File.WriteAllLines("myfile.htm", lines);
// With C# 3.5
File.WriteAllLines("myfile.htm", lines.ToArray());

I'll say that File.WriteAllText is a stupid-proof way to write a text file for C# >= 3.5.

File.WriteAllText("myfile.htm", @"<html><body>Hello World</body></html>");

I'll even say that File.WriteAllLines is stupid-proof enough to write bigger html without fighting too much with string composition. But the "good" version is only for C# 4.0 (a little worse version is C# >= 2.0)

List<string> lines = new List<string>();
lines.Add("<html>");
lines.Add("<body>");
lines.Add("Hello World");
lines.Add("</body>");
lines.Add("</html>");

File.WriteAllLines("myfile.htm", lines);
// With C# 3.5
File.WriteAllLines("myfile.htm", lines.ToArray());

如果创建文件时没有所有数据，我会使用 File.Create 然后打开该文件的 StreamWriter。
这是 MS 的一个示例，可能会对您有所帮助

class Test 
{
    public static void Main() 
    {
        string path = @"c:\temp\MyTest.txt";

        // Create the file.
        using (FileStream fs = File.Create(path, 1024)) 
        {
            Byte[] info = new UTF8Encoding(true).GetBytes("This is some text in the file.");
            // Add some information to the file.
            fs.Write(info, 0, info.Length);
        }

        // Open the stream and read it back.
        using (StreamReader sr = File.OpenText(path)) 
        {
            string s = "";
            while ((s = sr.ReadLine()) != null) 
            {
                Console.WriteLine(s);
            }
        }
    }
}

I would go with File.Create and then open a StreamWriter to that file if you dont have all the data when you create the file.
This is a example from MS that may help you

class Test 
{
    public static void Main() 
    {
        string path = @"c:\temp\MyTest.txt";

        // Create the file.
        using (FileStream fs = File.Create(path, 1024)) 
        {
            Byte[] info = new UTF8Encoding(true).GetBytes("This is some text in the file.");
            // Add some information to the file.
            fs.Write(info, 0, info.Length);
        }

        // Open the stream and read it back.
        using (StreamReader sr = File.OpenText(path)) 
        {
            string s = "";
            while ((s = sr.ReadLine()) != null) 
            {
                Console.WriteLine(s);
            }
        }
    }
}
