问题 This question already has answers here : How to serialize byte[] as simple JSON Array and not as base64 in JSON.net? (3 answers) Closed 3 years ago . public class MyClass { public byte[] Bytes{get;set;} } MyClass obj = new MyClass(); obj.Bytes = new byte[]{1,22,44,55}; string s_result = Newtonsoft.Json.JsonConvert.SerializeObject(obj); // my s_result looks like {"Bytes":"KQAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAAA="} I want result like "Bytes":"1,22,44,55" I did work around for this by

问题 I've just recently started with Java and have gotten to Arrays. from what I can tell there are two ways of creating Arrays. The first method makes the most sense to me coming from a python background. type[] ArrayName; i.e. int[] agesOfParticipants; However a lot of resources online use a different method of creating arrays. ArrayList<ArrayType> Name = new ArrayList<ArrayType>; not only is this different but from what I can tell the term ArrayList is at least partially interchangeable

问题 I'd like to SELECT rows from a database table and group them using PHP instead of SQL based on a parameter (in this case by item). SQL: Clothes table id item owner 1 shoes joe 2 pants joe 3 hat joe 4 pants joe 5 hat tom SELECT * from Clothes where owner='joe' 1 shoes joe 2 pants joe 3 hat joe 4 pants joe Here's how I'd like the results to look after using PHP instead of SQL's GROUP BY item PHP : 1 shoes joe 2 pants joe //count 2 3 hat joe I'm sure there is a PHP array function for this I'm

问题 I'm getting stuck on getting min value from array. every time when I run it, the minimum value is still zero. I know that the index has to go to minus one, but i just don't know how should I apply it on the code. sorry for my poor English, I hope you guys can help me out! public partial class Form1 : Form { int[] numbers = new int[99]; int index = 0; public Form1() { InitializeComponent(); } private void Form1_Load(object sender, EventArgs e) { } public int Som() { //if the numbers are <99

问题 I have a vector like this : >> v = [1 1 1 2 2 3 4 4 4 4 4 5 5]' v = 1 1 1 2 2 3 4 4 4 4 4 5 5 The vector is sorted. There can be any number of each values. I need to find the index of the last occurence of each value. In this case, it would return this : answer = 3 % index of the last occurence of "1" 5 % index of the last occurence of "2" 6 % index of the last occurence of "3" 11 % index of the last occurence of "4" 13 % index of the last occurence of "5" 回答1: Thanks to @trumpetlicks, the

问题 I'm selecting a single column from my mysql database: $savedSQL = 'SELECT can_id FROM savedsearches WHERE user_id = "'.mysql_real_escape_string($user_id).'" AND insertTime >= "'.$lastSigTime.'"'; $savedQuery = mysql_query($savedSQL); And I'd like to return the values as a single dimension, enumerated array such that array[0] = row1, array[1] = row2, etc. When I put it into an array like this: while($savedResult = mysql_fetch_array($savedQuery)) { $savedArray[] = $savedResult; } It returns it
