Example of JavaScript arrays:
var array_1 = [["string 1", 2013, "string 2"], "string 3", ["string 4", , "string 5"]];
/* array_1[0][2] = "string 2" */
var array_2 = [1, , ["string 1", "string 2"]];
/* array_2[0][0] = 1 */
I need to parse JS arrays like it to c# jagged array or any other object that can access each child string by index easy, by function, with:
1 => "1")null become "" (string with length = 0).Can you help me how to do this? Thank you very much!
using Json.NET
// using
using Newtonsoft.Json.Linq;
string JSarray_1 = @"[[""string 1"", 2013, ""string 2""], ""string 3"", [""string 4"", , ""string 5""]]";
JObject j = JObject.Parse("{\"j\":" + JSarray_1 + "}");
MessageBox.Show((string)j["j"][0][2]); // "string 2"
See the C# language documentation: "Multidimensional Arrays (C#)"
string[,] items = new string[,] {{"string 1","string 2"},...};
I think what TuyenTk is looking for, and emigue is trying to describe is to use a library which does the "magic"(=parsing)
I'd recommend JSON.Net since it's the one I use all the time - but I guess there are plenty of these out there.
The linked page also includes some simple examples on how to use it.
About replacing null with emptystring:
var myValue = origValue ?? String.Empty;
if origValue is null myValue will be set to "", otherwise the expression will evaluate to origValue;
For further information on "??", or the "null-coalescing operator" as it's called, see the doc
string[][] items = new string[3][];
items [0] = new string[2];
items [1] = new string[1];
items [2] = new string[2];
items[0][0] = "string1";
items[0][1] = "string3";
items[1][0] = "string4";
items[2][0] = "string5";
items[2][1] = "string6";
OR
string[][] items = new string[][]
{
new string[] {"string1", "string3"},
new string[] {"string4"},
new string[] {"string5", "string6"}
};
If you need parse javascript arrays to c# arrays, You can serialize Javascript arrays to JSON and then deserialize JSON to C# array.
Previously, you need to do one transformation: replace "" by null in Javascript array representation as string.
Then, you can make something like this:
var JSArrayString = @"{"array_1": [["string 1", 2013, "string 2"], "string 3", ["string 4", null, "string 5"]]}";
var CSharpDict = SomeJSONLibrary.Deserialize(JSString);
var CSharpArray = CSharpDict["array_1"];
var myItem = CSharpArray[0][2];
JSArrayString to CSharpArray[0][2] is a long distance.
