如何将字节发送到方法? [英] how to send the bytes to a methods ?

问题描述

namespace sonar_proj
{
    public partial class son : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

       char[] a = new char[10];
       char y  = conversion(byte );
        private byte conversion(byte binval)
        {
            binval =(byte)~binval;
            byte temp = (byte)(((binval & 0xf0)>>4) |(byte)((binval &0x0f)<<4) );
            return temp;
        }




         its showin some error . can u plz sort out this error

推荐答案

1)您不能在另一个方法的中间声明一个方法.
将其移到Page_Load事件之外，一切都应该没问题.

2)您不能将类byte作为参数传递给转换例程-您需要传递一个值.

1) You can''t declare a method in the middle of another method.
Move it outside the Page_Load event, and all should be fine.

2) You can''t pass a class byte as a parameter to your conversion routine - you need to pass a value instead.

在此处阅读有关字节的信息:MSDN:字节 [

Read about Byte here: MSDN: Byte[^]

Example:

byte myByte = 255;

// For your program
char y  = conversion(myByte);

char用于字符. byte用于数字.根据我在这里阅读的内容，您仅在处理数字.因此，暂时完全忘记char并将其全部更改为byte.

然后，您有

char is for characters. byte is for numbers. From what I have read here, you''re dealing with numbers only. So forget about char completely for now and change it all to byte.

Then you have

byte y  = conversion(byte );

，该方法不起作用，因为您将类型作为参数传递，且期望的值类型为byte.更改为

, which doesn''t work because you pass a type as parameter where a value of type byte is expected. Change to

byte y = conversion(0x42);

.

"42"代表一些值.我不知道您真的要转换.将所需的内容放在convert()的括号之间.

.

The "42" represents some value. I don''t know what you really want to convert. Put whatever you want between the brackets of convert().
