我在asp Gridvidiew中有以下代码:
<asp:HyperLink ID="hlPSTNNum" CssClass="OrdRef" Text='<%# DataBinder.Eval(Container.DataItem, "PSTNNum")%>' runat="server" ToolTip='please click here to view the full record details'
NavigateUrl='<%#"https://THE URL IS HERE Searches/advancedsearchresults.asp?supplierid=" + Eval("Supplierid") + "&display1=IS%20Number&display2=Supplier&display3=Product&display4=Supplier%20Order%20Number&order1=order%20date&pstnnum=" + Eval("PSTNNum")%>' />
我认为Visual Studio 2012正在查询查询字符串部分中的分号(来自“pstnnum =”+ Eval(“PSTNNum”)%&gt;'/&gt;“并且我试图用\来逃避它们)保持VS快乐,但浏览器在每次逃脱时留下一个斜杠。
不确定这里的最佳做法,因为我还在削减我的编码牙齿......

我认为更合适的方法是这样的:
<asp:HyperLink ID="hlPSTNNum"
CssClass="OrdRef"
Text='<%# DataBinder.Eval(Container.DataItem, "PSTNNum")%>'
runat="server"
ToolTip='please click here to view the full record details'
NavigateUrl='<%#Server.HtmlEncode("https://THE URL IS HERE Searches/advancedsearchresults.asp?supplierid=" + Eval("Supplierid") + "&display1=IS Number&display2=Supplier&display3=Product&display4=Supplier Order Number&order1=order date&pstnnum=" + Eval("PSTNNum"))%>' />
请注意Server.HtmlEncode
的使用,然后使用您想要的实际值而不是直接编码的值。这将使在Visual Studio中构建变得容易,但确保在呈现时对其进行编码。
经过对微软代码的更多研究后,我发现RenderContents
类的基本HyperLink
方法将为您编码。该方法在内部调用另一个名为ResolveClientUrl
的方法,如下所示:
public string ResolveClientUrl(string relativeUrl)
{
if (this.DesignMode && this.Page != null && this.Page.Site != null)
{
IUrlResolutionService urlResolutionService = (IUrlResolutionService)this.Page.Site.GetService(typeof(IUrlResolutionService));
if (urlResolutionService != null)
{
return urlResolutionService.ResolveClientUrl(relativeUrl);
}
}
if (relativeUrl == null)
{
throw new ArgumentNullException("relativeUrl");
}
string virtualPathString = VirtualPath.GetVirtualPathString(this.TemplateControlVirtualDirectory);
if (string.IsNullOrEmpty(virtualPathString))
{
return relativeUrl;
}
string text = this.Context.Request.ClientBaseDir.VirtualPathString;
if (!UrlPath.IsAppRelativePath(relativeUrl))
{
if (StringUtil.EqualsIgnoreCase(text, virtualPathString))
{
return relativeUrl;
}
if (relativeUrl.Length == 0 || !UrlPath.IsRelativeUrl(relativeUrl))
{
return relativeUrl;
}
}
string to = UrlPath.Combine(virtualPathString, relativeUrl);
text = UrlPath.AppendSlashToPathIfNeeded(text);
return HttpUtility.UrlPathEncode(UrlPath.MakeRelative(text, to));
}
由于您的URL不是相对的,因此它应该一直到最后一行return
语句,所以老实说,您根本不需要编码它。这会将您的代码更改为:
<asp:HyperLink ID="hlPSTNNum"
CssClass="OrdRef"
Text='<%# DataBinder.Eval(Container.DataItem, "PSTNNum")%>'
runat="server"
ToolTip='please click here to view the full record details'
NavigateUrl='<%#"https://THE URL IS HERE Searches/advancedsearchresults.asp?supplierid=" + Eval("Supplierid") + "&display1=IS Number&display2=Supplier&display3=Product&display4=Supplier Order Number&order1=order date&pstnnum=" + Eval("PSTNNum")%>' />

不是100%确定这是否有效,但asp.net 4.5有&lt;%#:自动编码。您可以尝试并查看它是否有效,只需将&lt;%#更改为&lt;%#:
即可
