c# - EF Fluent API + two column composite uniqueness + autoincrement primary key -

-

  1. I use Fluent API I do not like comments.

  2. I always want to use an automation as my primary key, in all my tables.

  3. My columns require two columns, X and Y (where x is not the key of the orientation and the Y is not an auto key key), i.e.: not another line It can have X1 = X2 and Y1 = Y2 If I was not using an autoincrement key, then I would just create the keys of these two in this way: 

      modelbuilder Entity & lt; Foo & gt; () .HasKey (t = & gt; new {tX, TI}). Takelet ("FOS");   
     But, as I said in (2), I am using Auto Correction Primary Key  
      modelbuilder.Entity & lt; Foo & gt; () .HasKey (t = & gt; t.SomeLongId) .ToTable ("Foos"); How can I achieve this overall specificity in the Fluent API?  
     I want to get it written in SQL:  
      create tab 'fuse' (`id 'large (20) unknown call entanglement, ... primary key (`Id`), unique key (` x`, `y ')); You can get it and apply it using the 'HasColumnAnnotation (...)' method.    
     
     
      modelbuilder.Entity & lt; Foo & gt; (). Property (t = & gt; tx). Callman Annotation ("X", New Index Annotation (New Index Accruiter ("X") {ICU = True});   
     You can find more information

php - How can I cram 6+31 numeric characters into 22 alphanumeric characters? -

-
I have a 6 digit number and a 31-digit number (such as "234536" and "201103231043330478311223582826") that I The API needs to be crawled in the same 22-character alphanumeric field that uses PHP. I tried to convert each one to 32 (using custom code could not handle the base_convert () large number) and to connect with a single-character delimiter, but It only gives me 26 characters This is a restore API, so the letters should be URI-protected. I would like to do a database table cross with two references without reference to another reference value, if possible, any suggestions? Instead use a radix of 62. This will give you 22 characters for the top, 3.35 for the pre and 17.3 for the next. & gt; & Gt; & Gt; Math.log (10 ** 6) /math.log (62) 3.3474826039165504 & gt; & Gt; & Gt; Math.log (10 ** 31) /math.log (62) 17.295326786902177

logging - How can I log both the Request.InputStream and Response.OutputStream traffic in my ASP.NET MVC3 Application for specific Actions? -

-
For a specific set of tasks, I need to log in to the incoming request inputstream as well as outgoing response. is. I am using an ActionFilterAttribute for this and overriding the OnActionExecuted and OnResultExecuted methods. So I'm starting with this idea ... Public category ActionLoggerAttribute: ActionFilterArrbit {Public Override Zero On-Offed Execution (ActionActioned Contact Filter Filter) {base.OnActionAxecuted (FilterContext); HttpRequestBase request = filterContext.HttpContext.Request; // TODO: Log the request. InputStream} Public Override Zero OnResultExecuted (ResultExecutedContext FilterContext) {base.OnResultExecuted (filterContext); HTTPRPSPointBase Response = FilterContacts Hpptex response; // TODO: Log on Response.OutputStream}} Ideally I'll hook it up with enterprise library logging because I'm already using it for error logging. Am I reaching the input and output stream at the right time? Can I easily use the Enterprise Library to log i...
