asp.net-4.0

问题 I there a simple way when using ASP.NET 4.0 routing with Web Forms to produce a route that will act as some kind of wildcard? It seems to me that within WebForms, you have to specify a route for every page - I am looking for some kind of generic route that can be used where nothing specific is required, perhaps mapping directly from path to path so... http://somedomain.com/folder1/folder2/page would possibly map to folder1/folder2/page.aspx Any suggestions?

问题 I need to locate a fast, lightweight expression parser. Ideally I want to pass it a list of name/value pairs (e.g. variables) and a string containing the expression to evaluate. All I need back from it is a true/false value. The types of expressions should be along the lines of: varA == "xyz" and varB==123 Basically, just a simple logic engine whose expression is provided at runtime. UPDATE At minimum it needs to support ==, !=, >, >=, <, <= Regarding speed, I expect roughly 5 expressions to

问题 My ASP.NET application runs in IIS on my web server and uses Microsoft .NET Framework 4 Beta 2. (Its Application Pool is set to .NET Framework version .NET Framework v4.0.21006.)
