.NET 1.1 보안 문자 구현 컴파일러 오류

Question

저는 ASP.NET을 처음 사용했습니다. 내가/BuildCaptcha.aspx 보안 문자에 다음 코드 한 http://www.codekicks.com/2008/04/implement-simple-captcha-in-cnet.html

:

<%@ Page Language="C#" %> 
<%@ Import Namespace="System" %> 
<%@ Import Namespace="System.Drawing" %> 
<%@ Import Namespace="System.Drawing.Color" %> 
<%@ Import Namespace="System.Drawing.Imaging" %> 
<script language="C#" runat="server"> 
Bitmap objBMP = new Bitmap(60, 20); 
Graphics objGraphics = Graphics.FromImage(objBMP); 
objGraphics.Clear(Color.Wheat); 
objGraphics.TextRenderingHint = TextRenderingHint.AntiAlias; 
//' Configure font to use for text 
Font objFont = new Font("Arial", 8, FontStyle.Italic); 
string randomStr = ""; 
char[] myArray = new char[5]; 
int x; 
//That is to create the random # and add it to our string 
Random autoRand = new Random(); 
for (x = 0; x < 5; x++) 
{ 
    myArray[x] = System.Convert.ToChar(autoRand.Next(65,90)); 
    randomStr += (myArray[x].ToString()); 
} 
//This is to add the string to session, to be compared later 
Session.Add("RandomStr", randomStr); 
//' Write out the text 
objGraphics.DrawString(randomStr, objFont, Brushes.Red, 3, 3); 
//' Set the content type and return the image 
Response.ContentType = "image/GIF"; 
objBMP.Save(Response.OutputStream, ImageFormat.Gif); 
objFont.Dispose(); 
objGraphics.Dispose(); 
objBMP.Dispose(); 
</script> 

나는 다음과 같은 오류가 발생하고 클라이언트의 서버는 .NET 1.1을 실행하고 나는 여기에 설명 된 간단한 보안 문자를 구현하기 위해 노력하고 captcha 방문시/BuildCaptcha.aspx :

Compiler Error Message: CS1519: Invalid token '(' in class, struct, or interface member declaration 

Source Error: 

Line 7: Bitmap objBMP = new Bitmap(60, 20); 
Line 8: Graphics objGraphics = Graphics.FromImage(objBMP); 
Line 9: objGraphics.Clear(Color.Wheat); 
Line 10: objGraphics.TextRenderingHint = TextRenderingHint.AntiAlias; 
Line 11: //' Configure font to use for text 


Source File: \\...\captcha\BuildCaptcha.aspx Line: 9 

귀하의 도움에 감사드립니다.

Answer 1

대신 CodeProject의에서이 일을보십시오. 그것은 아주 잘 작동 CAPTCHA Image

당신은 방법, 예를 들어의 OnLoad에이 코드를 넣어야
