Question

求一过虑字符串中HTML标签及特殊符号的方法(asp.net)

要求写一个.cs方法
public string EncodeStr(string str){

return //处理后字符串;
}

Answer 1

using System;

/// <summary>
/// CleanString 的摘要说明。
/// </summary>
public sealed class CleanString
{

public static string htmlInputText( string inputString )//HTML过滤输入字符串
{
if ((inputString != null) && (inputString != String.Empty ))
{
inputString = inputString.Trim();
inputString = inputString.Replace("'",""");
inputString = inputString.Replace("<","<");
inputString = inputString.Replace(">",">");
inputString = inputString.Replace(" "," ");
inputString = inputString.Replace("\n","<br>");
return inputString.ToString();
}
return "";
}

public static string htmlOutputText( string inputString )//HTML还原字符串
{
if ((inputString != null) && (inputString != String.Empty ))
{
inputString = inputString.Trim();
inputString = inputString.Replace(""","'");
inputString = inputString.Replace("<","<");
inputString = inputString.Replace(">",">");
inputString = inputString.Replace(" "," ");
inputString = inputString.Replace("<br>","\n");
return inputString.ToString();
}
return "";
}

}

把这个写成一个类 想在哪里用随便掉就好了！很方便的...!

Answer 2

不需要过滤，Asp.net中有个repeter控件，使用它的好处是就是去除了HTML标签，不会生成它，至于他的用法你可以在网上查下，这一下子说不清楚

Answer 3

用server.HtmlEncode("脚本代码")
可以把客户端输入的脚本代码，原样显示不执行!

Answer 4

你的意识是过滤 特殊符号 还有HTML标签吗?
