问题描述

亲爱的朋友:

我有一个来自文本框的字符串.我想将此字符串以ASCI格式写入文件.我使用了各种方法，但没有得到任何结果.
例如:

Dear Friend:

I have a string that comes from a textbox. I want to write this string in the format of ASCI to a file. I use various method but i do not get any result.
for example:

private static Encoding encoding = Encoding.ASCII;

private static byte[] CSTB( string cod, Encoding enc )
{
    byte[] transformacion = enc.GetBytes( cod );
    return transformacion;
}

private void btn_CreateNewCard_Click( object sender , EventArgs e )
{
FileInfo finfo = new FileInfo( path );


    using(FileStream fs = finfo .Open( FileMode .Open ,FileAccess .Write ,   FileShare .ReadWrite ))
    try
    {

        fs .Write( CSTB( "Moha",encoding  ),0, CSTB( "Moha",encoding  ).Lenght);
     }
}

我的代码正确吗?
为什么单击按钮时会看到原始文本("Moha")?

Is that my code correct?
Why I see the original text ("Moha") when I click my button?

推荐答案

为什么要以ascii格式写入文件?

试试这个.

Why you want to write the file in ascii format?

Try this.

File.WriteAllText(pathOfFile, "Moha", Encoding.ASCII);

首先了解ASCII的含义.请阅读此链接.


如果您期望输出像4D-4F-6F-6E .........
您正在获取每个字符的十六进制值.

阅读此以获取ascii中每个字符的十六进制值.


要使用c#实现以上目标，请尝试以下代码:

first understand what ASCII mean.read this link.


if u are expecting output like 4D-4F-6F-6E.........
u r getting each character''s hex value.

read this to get hex value of each character in ascii.


To achieve above using c# try this code:

<pre lang="c#">
string EncodedString=BitConverter.ToString(Encoding.ASCII.GetBytes(<ur string>));
