初学~搞了1天了~关于将textbox中的文字转换为ACSII码!高手麻烦给个例子!编译成功就马上给分!
就是从textbox里面输入的文字转换为ASCII码!或者是将一个数组里面的中文转换为ASCII码!编译成功马上给分!

------解决方案--------------------
关于ASCII和字符的转换，你看看下面这段代码。


using System;
using System.Text;

namespace Encoding_Examples
{
using System;
using System.Text;

class EncodingExample
{
public static void Main()
{
// Create an ASCII encoding.
Encoding ascii = Encoding.ASCII;

// A Unicode string with two characters outside the ASCII code range.
String unicodeString =
"This unicode string contains two characters " +
"with codes outside the ASCII code range, " +
"Pi (\u03a0) and Sigma (\u03a3). ";
Console.WriteLine( "Original string: ");
Console.WriteLine(unicodeString);

// Save the positions of the special characters for later reference.
int indexOfPi = unicodeString.IndexOf( '\u03a0 ');
int indexOfSigma = unicodeString.IndexOf( '\u03a3 ');

// Encode the string.
Byte[] encodedBytes = ascii.GetBytes(unicodeString);
Console.WriteLine();
Console.WriteLine( "Encoded bytes: ");
foreach (Byte b in encodedBytes)
{
Console.Write( "[{0}] ", b);
}
Console.WriteLine();

// Notice that the special characters have been replaced with
// the value 63, which is the ASCII character code for '? '.
Console.WriteLine();
Console.WriteLine(
"Value at position of Pi character: {0} ",
encodedBytes[indexOfPi]
);
Console.WriteLine(
"Value at position of Sigma character: {0} ",
encodedBytes[indexOfSigma]
);

// Decode bytes back to a string.
// Notice missing the Pi and Sigma characters.
String decodedString = ascii.GetString(encodedBytes);
Console.WriteLine();
Console.WriteLine( "Decoded bytes: ");
Console.WriteLine(decodedString);
}
}
}


------解决方案--------------------
string s = " ";
foreach (byte vByte in Encoding.Default.GetBytes(textBox1.Text))
s += "% " + vByte.ToString( "X2 ");
Text = s;

------解决方案--------------------
for (int i=0; i < textbox1.Len; i++)
{
int b = (char)(textbox1.text.mid(i,1));
debug.print b;
}
------解决方案--------------------
//获得汉字的区位码
byte[] array = new byte[2];
array = System.Text.Encoding.Default.GetBytes( "啊 ");

int i1 = (short)(array[0] - '\0 ');
int i2 = (short)(array[1] - '\0 ');

//unicode解码方式下的汉字码
array = System.Text.Encoding.Unicode.GetBytes( "啊 ");
i1 = (short)(array[0] - '\0 ');
i2 = (short)(array[1] - '\0 ');

//unicode反解码为汉字
string str = "4a55 ";
