怎样调用app_code里的cs类!!!!!!!!!
CS类如下:
/**//// <summary>
/// FilterRealProxy类：一个真实代理, 拦截它所代理对象中方法的返回值，并对需要过滤的返回值进行过滤。
/// </summary>
public class FilterRealProxy:RealProxy
{
private MarshalByRefObject target;
public FilterRealProxy(MarshalByRefObject target):base(target.GetType())
{
this.target=target;
}
public override IMessage Invoke(IMessage msg)
{
IMethodCallMessage callMsg=msg as IMethodCallMessage;
IMethodReturnMessage returnMsg = RemotingServices.ExecuteMessage(target,callMsg);
//检查返回值是否为String,如果不是String,就没必要进行过滤
if(this.IsMatchType(returnMsg.ReturnValue))
{
string returnValue=this.Filter(returnMsg.ReturnValue.ToString(),returnMsg.MethodName);
return new ReturnMessage(returnValue,null,0,null,callMsg);
}
return returnMsg;
}
protected string Filter(string ReturnValue,string MethodName)
{
MethodInfo methodInfo=target.GetType().GetMethod(MethodName);
object[] attributes=methodInfo.GetCustomAttributes(typeof(StringFilter),true);
foreach (object attrib in attributes)
{
return FilterHandler.Process(((StringFilter)attrib).FilterType,ReturnValue);
}
return ReturnValue;
}
protected bool IsMatchType(object obj)
{
return obj is System.String;
}
}
/**//// <summary>
/// StringFilter类：自定义属性类, 定义目标元素的过滤类型
/// </summary>
public class StringFilter:Attribute
{
protected FilterType _filterType;
public StringFilter(FilterType filterType)
{
this._filterType=filterType;
}
public FilterType FilterType
{
get
{
return _filterType;
}
}
}
/**//// <summary>
/// 枚举类：用于指定过滤类型，例如：对script过滤还是对html进行过滤？
/// </summary>
[Flags()]
public enum FilterType
{

Iframe=5,
Frameset=6,
Src=7,
BadWords=8,
//Include=9,
All=16
}
/**//// <summary>

/// </summary>
public class FilterHandler
{
private FilterHandler()

}
public static string Process(FilterType filterType,string filterContent)

break;
//case FilterType.Include:

// break;

filterContent=FilterBadWords(filterContent);
break;
case FilterType.All:
filterContent=FilterAll(filterContent);
break;
default:
//do nothing
break;
}
return filterContent;
}
public static string FilterScript(string content)
{
string commentPattern = @ "(? 'comment ' <!--.*?--[ \n\r]*> ) " ;
string embeddedScriptComments = @ "(\/\*.*?\*\/|\/\/.*?[\n\r]) " ;

public static string FilterHtml(string content)

.......太长省略
//移除非法或不友好字符
private static string FilterBadWords(string chkStr)
{
//这里的非法和不友好字符由你任意加，用“|”分隔，支持正则表达式,由于本Blog禁止贴非法和不友好字符，所以这里无法加上。
string BadWords=@ " ";
if (chkStr == " ")
{
return " ";
}
string[] bwords = BadWords.Split( '# ');
int i,j;
string str;
StringBuilder sb = new StringBuilder();
for(i = 0; i < bwords.Length; i++)
{
str=bwords[i].ToString().Trim();
string regStr,toStr;
regStr=str;
Regex r=new Regex(regStr,RegexOptions.IgnoreCase | RegexOptions.Singleline| RegexOptions.Multiline);
Match m=r.Match(chkStr);
if(m.Success)
{
j=m.Value.Length;
sb.Insert(0, "* ",j);
toStr=sb.ToString();
chkStr=Regex.Replace(chkStr,regStr,toStr,RegexOptions.IgnoreCase | RegexOptions.Singleline| RegexOptions.Multiline);
}
sb.Remove(0,sb.Length);
}
return chkStr;
}
public static string FilterAll(string content)
{
content = FilterHtml(content);
content = FilterScript(content);
content = FilterAHrefScript(content);
content = FilterObject(content);
content = FilterIframe(content);
content = FilterFrameset(content);
content = FilterSrc(content);
content = FilterBadWords(content);
//content = FilterInclude(content);
return content;
}
}
我在index.cs里调用如下:
FilterRealProxy Filter = new FilterRealProxy();
tb_spec.Text = Filter.FilterHtml(dr[ "spec "].ToString());
错误如下:编译器错误信息: CS0117: “FilterRealProxy”并不包含“FilterHtml”的定义
[解决办法]
using 它的命名空间,直接调用~~
[解决办法]
static
cs.*就行了，代码太长不看了，说说什么问题
[解决办法]
哈哈，也真的服了楼主哦，这么长的代码也贴出来了啊
[解决办法]
看一下他的类的命名空间,引用一下,就可调用 了
[解决办法]
FilterRealProxy:RealProxy
是不是 RealProxy的FilterHtml 需要重写？而你没有重写造成的？
