问题 I am Continuing my question Previous Question . In my last question @p.s.w.g gives exact solution as i want . Now another situation comes into my mind that suppose we need to search greater then 4 in a condition then what will we do . Detail In my last question i said the criteria will goes up to 1-4 , Suppose we include more criteria and give user a option to select 4+ and we will return all data where Bedroom is greater then four . What we will do in this case . Suppose i got this in my

问题 I want to simply execute pure MongoDB queries via MongoDb 10Gen's .net(c#) driver. For example . I want to use below command on driver db.people.update( { name:"Joe" }, { $inc: { n : 1 } } ); I am not sure how can i do this. I am not interested in how to do via high level api classes. 回答1: The C# driver (or any other driver) is not intended to "directly" run mongo shell commands. That's what the shell is for. What you need to do is translate the mongo shell commands into the equivalent C#

问题 I am studying algorithms and I have two bubble sort functions/methods and both of them provide similar result. Can please someone tell me something more about them, such as performance etc? public void BubbleSort() { int temp; for (int outer = upper; outer >= 1; outer--) { for (int inner = 0; inner <= outer - 1; inner++) { if ((int)arr[inner] > arr[inner + 1]) { temp = arr[inner]; arr[inner] = arr[inner + 1]; arr[inner + 1] = temp; } } } } public void BubbleSor2() { int temp; for (int outer =

问题 I've 'googled' the life out of this issue today with zero resolve! I am trying to build a very simple Google Analytics data request console app using a Service account. I have set up all the required details in the Google Developers Console but I am getting the following error: An unhandled exception of type 'Google.Apis.Auth.OAuth2.Responses.TokenResponseException' occurred in Google.Apis.dll Additional information: Error:"invalid_grant", Description:"", Uri:"" Below is the code in my

问题 I have been reading Joseph Albahari's brilliant book on C# 4.0 and I came across this class: public static class PredicateBuilder { public static Expression<Func<T, bool>> True<T> () { return f => true; } public static Expression<Func<T, bool>> False<T> () { return f => false; } public static Expression<Func<T, bool>> Or<T> (this Expression<Func<T, bool>> expr1, Expression<Func<T, bool>> expr2) { var invokedExpr = Expression.Invoke (expr2, expr1.Parameters.Cast<Expression> ()); return

问题 Is there a way to know if the byte[] has been compressed (or not) by GzipStream .net class? EDIT: Just want to know if the byte[] array has been compressed (since I will always be using GzipStream to compress and decompress) 回答1: A GZipStream is a DeflateStream with an additional header and trailer. The format is specified in RFC 1952. The .NET 4.0 GZipStream class writes the following bytes as header: byte[] headerBytes = new byte[] { 0x1f, 0x8b, 8, 0, 0, 0, 0, 0, 4, 0 }; if

问题 All the C# codes available over net are just for read and loading XML and XSD . XmlDocument xmlDocument = new XmlDocument(); xmlDocument.Load(@"D:\XML\Sample.xml"); xmlDocument.Schemas.Add("http://www.w3.org/2001/XMLSchema", @"D:\XML\Sample.xsd"); xmlDocument.Schemas.Compile(); ValidationEventHandler eventhandler = new ValidationEventHandler(ValidationEventHandler); xmlDocument.Validate(eventhandler); if (valid == true) { label1.Text = "Xml Got Validated!!"; } void ValidationEventHandler
