What do you mean by:
char y = conversion(byte );

Solution 1

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.

Can you please tell me how to send the values ???

OriginalGriff 23-Apr-12 3:27am

byte b = 123;
char y = (char) conversion(b);

You need to cast the conversion return value to a char or the compiler will rightly complain!

Its again throwing eror called Error 1 Expected class, delegate, enum, interface, or struct

OriginalGriff 23-Apr-12 3:34am

You have probably put the code in the wrong place! Check your code: comment out those two lines so that it compiles clean - it won't work yet, but as soon as it compiles cleanly press CTRL+K CTRL+D which should reformat your whole document so that the indentation is correct. These two lines of code need to be inside the "{" and "}" immediately following the

protected void Page_Load(object sender, EventArgs e)

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

char[] a = new char[10];
byte b = 123;
char y = (char) conversion(b);
}
private byte conversion(byte binval)
{
binval = (byte)~binval;
byte temp = (byte)(((binval & 0xf0) >> 4) | (byte)((binval & 0x0f) << 4));
return temp;
}
}

}
this is my program . Still Iam able to bug the error . Can u tell me why is its so.

OriginalGriff 23-Apr-12 3:52am

What is the error? when I run your code, I get y == 72 which is what I would expect.

Rahul_Chand 23-Apr-12 4:50am

sorry for the delay ...No error is showing but its showing ocalhost:1039/son.aspx in google chrome.

OriginalGriff 23-Apr-12 4:56am

Which may not have anything to do with the code above...:laugh:
Comment out all the code for testing: get it working without strange browser messages first!

Solution 2

Read about Byte here: MSDN: Byte[^]

Example:

C#

byte myByte = 255;

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

Sandeep thnks for your concern but even though by adding byte myByte = 255;

// For your program
char y = conversion(myByte); I am gettin the error called Error 1 Expected class, delegate, enum, interface, or struct

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

C#

byte y  = conversion(byte );

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

C#

byte y = conversion(0x42);

.

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

how to send the bytes to a methods ?
