阅读更多关于 Performance of System.IO.ReadAllxxx / WriteAllxxx methods

问题 Is there any performance comparison of System.IO.File.ReadAllxxx / WriteAllxxx methods vs StreamReader / StremWriter classes available on web. What you think is the best way(from a performance perspective) to read/write text files in .net 3.0? When I checked the MSDN page of System.IO.File class , in the sample code MS is using StreamReader / StreamWriter for file operations. Is there any specific reason for avoiding File.ReadAllxxx / WriteAllxxx methods, even though they look much easier to

.NET 3.5 vs. .NET 3.0

问题 I want to write a program in WPF but not sure should I target .net35 or .net30. The advantages of .net35 are obvious. But still, I see one major advantage of .net30 -- it's built into Vista, so, the people using Windows Vista will not have to download and install the framework. Do you think the advantages of .net35 outweigh the hassle of downloading ~200 megas and installing in? P.S. Actually, I don't need advanced stuff like linq, etc. So, I guess .net30 will suffice. Or am I missing

WCF ChannelFactory and Channel caching in ASP.NET client application

阅读更多关于 WCF ChannelFactory and Channel caching in ASP.NET client application

问题 I'm building a series of WCF Services that are going to be used by more than one application. Because of that I'm trying to define a common library to access WCF services. Knowing that each service request made by different users should use a different Channel I'm thinking in cache the Channel per-request ( HttpContext.Current.Items ) and cache the ChannelFactory used to create the channel per Application ( HttpApplication.Items ) since I can create more than one channel with the same
