Silverlight xap cache processing method

Comment out Index. aspx

The code is as follows:	Copy code
<Param name = "source" value = "ClientBin/xxxxxx. xap"/>

Add the following C # code:

 

The code is as follows:

Copy code

<% // Modify 2011.11.07 to solve the xap cache problem String strSourceFile = @ "ClientBin/xxxxxx. xap "; String param; If (System. Diagnostics. Debugger. IsAttached) Param = "<param name =" source "value =" "+ strSourceFile +" "/> "; Else             { String xappath = HttpContext. Current. Server. MapPath (@ "") + @ "" + strSourceFile; DateTime xapCreationDate = System. IO. File. GetLastWriteTime (xappath ); Param = "<param name =" source "value =" "+ strSourceFile + "? Ignore =" + XapCreationDate. ToString () + ""/> ";             } Response. Write (param ); %>

When the xap is updated, the last modification time of the xap file is used to determine whether the xap is a newly generated xap, so as to control whether to read the xap in the cache or download the xap on the server.
