问题 I am comparing two xml and I have to print the difference. How can I achieve this using LINQ. I know I can use XML diff patch by Microsoft but I prefer to use LINQ . If you have any other idea I will implement that //First Xml <Books> <book> <id="20504" image="C01" name="C# in Depth"> </book> <book> <id="20505" image="C02" name="ASP.NET"> </book> <book> <id="20506" image="C03" name="LINQ in Action "> </book> <book> <id="20507" image="C04" name="Architecting Applications"> </book> </Books> /

问题 I'm writing unit tests for checking some XML builder. Now I'm running into the problem of syntactical differences between the expected result and the actual result, despite their identical semantics. Example: Expected result: <parent><child attr="test attribute">text here</child></parent> Actual result: <parent> <child attr="test attribute"> text here </child> </parent> I tried normalizing the xml using XmlUtil.serialize(), however this seems to keep the whitespaces, leaving syntactical

问题 How to compare multidimensional arrays? Just true/false. double[,] data1 = new double[,] { { 1, 2 }, { 3, 4 }, { 5, 6 }, { 7, 8 } }; double[,] data2 = new double[,] { { 1, 2 }, { 3, 4 }, { 5, 6 }, { 7, 8 } }; //bool compare = data1.SequenceEqual(data2); Is there way to compare 2d arrays like 1d array ? data1.SequenceEqual(data2); I have to compare every second, so easiest way will be great. Thanks a lot. 回答1: A multidimensional array can be used in linq as one dimensional enumerable. You just

问题 I 'm writing test cases for the first time in visual studio c# i have a method that returns a list of objects and i want to compare it with another list of objects by using the Assert.AreEqual() method. I tried doing this but the assertion fails even if the two objects are identical. I wanted to know if this method, the two parameters are comparing references or the content of the object, Do I have to overload the == operator to make this work? 回答1: If you are using NUnit this is what the

问题 I am trying to implement a binary search using objective-c blocks. I am using the function indexOfObject:inSortedRange:options:usingComparator: . Here is an example. // A pile of data. NSUInteger amount = 900000; // A number to search for. NSNumber* number = [NSNumber numberWithInt:724242]; // Create some array. NSMutableArray* array = [NSMutableArray arrayWithCapacity:amount]; for (NSUInteger i = 0; i < amount; ++i) {; [array addObject:[NSNumber numberWithUnsignedInteger:i]]; }

问题 How do I check if two objects, e.g. dataframes, are value equal in R? By value equal, I mean the value of each row of each column of one dataframe is equal to the value of the corresponding row and column in the second dataframe. 回答1: It is not clear what it means to test if two data frames are "value equal" but to test if the values are the same, here is an example of two non-identical dataframes with equal values: a <- data.frame(x = 1:10) b <- data.frame(y = 1:10) To test if all values are

问题 #include <iostream> using namespace std; int main() { char word[10]="php"; char word1[10]="php"; if(word==word1){ cout<<"word = word1"<<endl; } return 0; } I don't know how to compare two char strings to check they are equal. My current code is not working. 回答1: Use std::string objects instead: #include <iostream> #include <string> using namespace std; int main() { string word="php"; string word1="php"; if(word==word1){ cout<<"word = word1"<<endl; } return 0; } 回答2: Use strcmp. #include

问题 I want to compare 2 Realm object Lists with each other to see if they are identical.

问题 Many thanks for reading. Apologies for what I'm sure is a simple task. I have a dataframe: (Edited: Added extra column not to be included in comparison) b = c(5, 6, 7, 8, 10, 11) c = c('david','alan','pete', 'ben', 'richard', 'edd') d = c('alex','edd','ben','pete','raymond', 'alan') df = data.frame(b, c, d) df b c d 1 5 david alex 2 6 alan edd 3 7 pete ben 4 8 ben pete 5 10 richard raymond 6 11 edd alan I want to compare the group of columns c and d with the group of columns d and c . That is

问题 I have 2 excel files and i wanted to compare the contents and highlight the differences. For example: first file... name|age abc|123 def|456 second file... name|age abc|123 def|456 ghi|789 - this being the differece is there any third party libraries to do this? or what would be the best way to do it? 回答1: Like DaDaDom said Apache POI is what you are looking for.
