c# - Using ProtoBuf-net to deseriailize a derived type (dictionary) does not properly set object fields -

-

I am attempting to deserialize an object whose class meets the dictionary & lt; String, int & gt; with string member field 

  Public class TempClass: dictionary & lt; String, int & gt; {Public string version; Public Tempelas () {}} I have written a unit test to capture the problem in which I am running: member field is not set, either serializing or deserializing ( / With a byte []) this test with the protofuf-net fails in the last  assurance  when it is verified that the deserialized  version  is set correctly it is always appropriate  is set to  null  instead of "someVersion" .   [testclass] Public class serial exam {[TestMethod] Public Zero TestMethod1 () {string newVersion = "someVersion"; TempClass Basic = New TempClass () {{"a", 2}, {"b", 3}, {"c", 1},}; Original. Version = new version; Byte [] serialized = serial (original); TempClass deserialized = desialize (sorted); // validate foreach (original pair originally) {Assert.IsTrue (deserialized.ContainsKeys (pair.key)); Assurance First (pair value, deserialized [couple.ca]); ) Doubt. All (new version, original version, "the original mapping version is not set correctly"); Decide. Aurequual (new version, deserialized.Version, "deserialized version does not match"); } Private static TempClass Deserialize (byte [serialized]) {TempClass deserialized; (MemoryStream MS = Using new memorystream ()) {ms.Write (sorted, 0, sorted. Length); Ms.osition = 0; Deserialized = Serializer Dairyialize & lt; TempClass & gt; (M / s); } Deserialized return; } Private static byte [] Serialize (Tempe class mapping) {byte [] serialized; (MemoryStream MS = new memorystream ()) using {Serializer.Serialize (MS, Mapping); Serialized = ms.ToArray (); } Return serialized; }}   
 I have not tried the same work with  BinaryFormatter  and  DataContractSerializer  for any benefit < / P> 
  Follow-up question:  Instead, I can redefine the  TempClass  in this way, always, the area is right from the original  Instead of being set to version , the constructor is always called instead how can I deserialize and ring the constellation without creating a new  version  If only the original Make a copy?  
  Public class TempClass: dictionary & lt; String, int & gt; {Public string version; Public TempClass () {Version = DateTime.UtcNow.ToString ("s"); } This effect may be related to the internal receipt of the ordering type of the IDV in the Protocol;}}    
 
 
. You can add version data to the dictionary or you can rewrite your DTO object like this sample. If you use this data object, it will correct your exam:  
  [ProtoContract] Public class TempClass {[ProtoMember (1)] Public dictionary & lt; String, int & gt; Information; [Proto member (2)] public string version; Public Templas () {}}   
 The third way is to write your own serialization.

I am trying to learn PDO, now I have written this small code, but it gives me a serious error: Fatal error: Call a member function at a non-object dot () ... $ con = new mysqli ("127.0.0.1", "root", "", "csvdangercheck"); $ Query = $ con- & gt; ("Id,` var1`, `var2`) values ​​(" id,: var1,: var2) ";); $ query- & gt; bypass pattern (': id', $ id); $ query- & gt; BindParam (': var1', $ VAL1); $ Query- & gt; bindParam (': var2', $ val2); $ Query-> Executed (); I Trying to use print_r ($ con-> errorInfo ()) but Fatal error: Undefined method mysqli :: errorInfo ( ) ... can someone tell me what am I missing? Flaffeh said, you have PDO Missing Mysqy, try it: $ con = new PDO ('mysql: host = 127.0.0.1; dbname = csvdangercheck', 'root', '');

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...
