How to get file's detail in the form of array in C# (windows form application)?

Question

I wanted to upload file using C# for which I need its Name, Type and size etc as an example given below. Please let me know, how can I do that.

[file2] => Array
        (
            [name] => MyFile.jpg
            [type] => image/jpeg
            [tmp_name] => /tmp/php/php6hst32
            [error] => UPLOAD_ERR_OK
            [size] => 98174
        )
)

Here is my existing code:

private void choosFileBtn_Click(object sender, EventArgs e) {
    OpenFileDialog ofdChoos = new OpenFileDialog(); 

    if (ofdChoos.ShowDialog() == DialogResult.OK) 
    { 
        System.Net.WebClient Client = new System.Net.WebClient(); 
        // Client.Headers.Add("Content-Type", "binary/octet-stream"); 

        var sourceString = ofdChoos.FileName.Replace(@"\", @"/"); var source = @"" + sourceString;
        var result = Client.UploadFile("https://zaffarology.com/upload.php", "POST", @source); 

        string s = System.Text.Encoding.UTF8.GetString(result, 0, result.Length); 
    } 
}

What have you tried? where did you get stuck? what did you google? — BugFinder, Oct 11 '18 at 12:55
That is PHP. Are you trying to say you want to upload to a php script from C#? — Cory, Oct 11 '18 at 12:56
Well, that bit accepts a file, so you want to accept files via C# or upload the file via C#? You still aren't clear. If you can post the full PHP then that would help. — Cory, Oct 11 '18 at 12:58
[FileInfo](https://learn.microsoft.com/en-us/dotnet/api/system.io.fileinfo?view=netframework-4.7.2) would seem like a good place to start your research... — Diado, Oct 11 '18 at 12:58
@BugFinder, Actually I need answer of this [Question](https://stackoverflow.com/questions/52539590/how-to-upload-some-files-of-any-type-to-online-server-by-sending-data-to-php-api) but no one was replying — J Smith, Oct 11 '18 at 13:00
@Cory, I wanted to upload file to online server using PHP API which requires file detail like file's type, size, name etc in the form of array in C#. That's why I posted PHP example — J Smith, Oct 11 '18 at 13:03
The question you mentioned that no-one was replying to has two duplicates marked ([1](https://stackoverflow.com/questions/16416601/c-sharp-httpclient-4-5-multipart-form-data-upload), [2](https://stackoverflow.com/questions/42212406/how-to-send-a-file-and-form-data-with-httpclient-in-c-sharp)), both of which have accepted answers which look useful at the very least. — Diado, Oct 11 '18 at 13:05
@JSmith there are bits of info, but it just doesnt seem like you've done anything yourself. The info you require has been offered to you but not in a "type this" format. — BugFinder, Oct 11 '18 at 13:35
@JSmith I can, I’m away from the computer. I’ll check back in a bit — Cory, Oct 11 '18 at 13:44
@Cory Thank You, I have solved the issue but facing another. I have got the required array by the following code(I'll share in next comment) — J Smith, Oct 11 '18 at 16:29
`private void choosFileBtn_Click(object sender, EventArgs e) {OpenFileDialog ofdChoos = new OpenFileDialog(); if (ofdChoos.ShowDialog() == DialogResult.OK) { System.Net.WebClient Client = new System.Net.WebClient(); // Client.Headers.Add("Content-Type", "binary/octet-stream"); var sourceString = ofdChoos.FileName.Replace(@"\", @"/"); var source = @"" + sourceString;` — J Smith, Oct 11 '18 at 16:31
`var result = Client.UploadFile("https://zaffarology.com/upload.php", "POST", @source); string s = System.Text.Encoding.UTF8.GetString(result, 0, result.Length); } }` — J Smith, Oct 11 '18 at 16:32
@Cory Sorry for pacing code in two comments due to characters limit. The problem is Type is not coming correct as in [file2] => Array ( [name] => MyFile.jpg [type] => image/jpeg [tmp_name] => /tmp/php/php6hst32 [error] => UPLOAD_ERR_OK [size] => 98174 ) ) — J Smith, Oct 11 '18 at 16:50
@JSmith, you can edit your post. I've edited it, waiting for a peer review then it will be active. I'll take a look now. — Cory, Oct 11 '18 at 17:37
@JSmith do you have access to the PHP file? Can you post it? Are you able to modify it to make it easier for you? — Cory, Oct 11 '18 at 17:43
@Cory, No I don't have access to PHP file, I can access it only by upload.php — J Smith, Oct 12 '18 at 09:24
@Cory I got every thing in array correctly but my file type is not coming correctly — J Smith, Oct 12 '18 at 09:26
