我使用的是作为的VirtualPathProvider这个讨论中加载从数据库剃刀观点的文章。
问题是,认为负荷,剃刀标记不被解析的时候。 它被在页面上呈现的正是这样"@inherits System.Web.Mvc.WebViewPage hello world
”
对于这个例子,我已经硬编码到由返回的串GetContent()
方法。
这里是我的代码:
public class MvcVirtualPathProvider : VirtualPathProvider {
// virtualPath example >> "~/Views/View/21EC2020-3AEA-1069-A2DD-08002B30309D.cshtml"
private static bool IsPathVirtual(string virtualPath)
{
string path = VirtualPathUtility.ToAppRelative(virtualPath);
// returns true if the path is requested by the "ViewController" controller
if (path.StartsWith("~/Views/TextualReporting/db/", StringComparison.InvariantCultureIgnoreCase))
{
return true;
}
return false;
}
public override bool FileExists(string virtualPath) {
if (IsPathVirtual(virtualPath)) {
SimpleVirtualFile file = (SimpleVirtualFile)GetFile(virtualPath);
if (file.Exists) {
return true;
}
return false;
}
return Previous.FileExists(virtualPath);
}
public override VirtualFile GetFile(string virtualPath) {
if (IsPathVirtual(virtualPath)) {
return new SimpleVirtualFile(virtualPath);
}
return Previous.GetFile(virtualPath);
}
// Simply return the virtualPath on every request.
public override string GetFileHash(string virtualPath, System.Collections.IEnumerable virtualPathDependencies) {
if (IsPathVirtual(virtualPath)) {
return virtualPath;
}
return base.GetFileHash(virtualPath, virtualPathDependencies);
}
private class SimpleVirtualFile : VirtualFile {
private string content;
public bool Exists {
get { return (content != null); }
}
public SimpleVirtualFile(string virtualPath)
: base(virtualPath) {
GetContent();
}
public override Stream Open() {
ASCIIEncoding encoding = new ASCIIEncoding();
return new MemoryStream(encoding.GetBytes(this.content), false);
}
protected void GetContent() {
if (IsPathVirtual(VirtualPath)) {
this.content = "@inherits System.Web.Mvc.WebViewPage \r\n hello world";
}
}
}
// just implement the default override and return null if the path is a Virtual Path
public override CacheDependency GetCacheDependency(string virtualPath,
System.Collections.IEnumerable virtualPathDependencies, DateTime utcStart) {
if (IsPathVirtual(virtualPath)) {
return null;
}
return Previous.GetCacheDependency(virtualPath, virtualPathDependencies, utcStart);
}
}
