How do i use HTTP PUT to upload files?

Im using C# code to send the request

Код:
var response = ZennoPoster.HTTP.Request(ZennoLab.InterfacesLibrary.Enums.Http.HttpMethod.PUT,
"link",
"",
"application/x-www-form-urlencoded",
instance.GetProxy(),
"",
ZennoLab.InterfacesLibrary.Enums.Http.ResponceType.HeaderAndBody,
AdditionalHeaders: new []{"Authorization:Bearer " + oauth" }
);

return response;
how do i upload files with this?
or is there a better alternative?

Thanks in advance

It's the same as POST with multipart:
var response = ZennoPoster.HTTP.Request(ZennoLab.InterfacesLibrary.Enums.Http.HttpMethod.PUT,
"https://httpbin.org/put",
@"-----------------------------77748066757751
Content-Disposition: form-data; name=""file""; filename=""cat.jpg""
Content-Type: image/jpeg

C:\Downloads\multipart\cat.jpg
-----------------------------77748066757751--",
"multipart/form-data",
"",
"",
ZennoLab.InterfacesLibrary.Enums.Http.ResponceType.BodyOnly
);
return response;

Код:

project.Variables["url_upload"].Value,
@"-----------------------------77748066757751

Content-Type: application/x-rar-compressed

C:\папка\папка\123.rar

return response;
Использую данный код, в яндекс диск rest api, rar создаётся, но не закачивается.
При скачивании битый архив. В чём может быть проблема? С txt та же беда, создаётся новый файл с текстом директории (C:\папка\папка\123.txt).
Хотя в файле 123.txt - лежит другой текст

Код:
PUT /a/otpusk.avi HTTP/1.1
Host: webdav.yandex.ru

Thanks for the help but i dont think its working for me...

When i check the request traffic, this is what the request body looks like when i do it on the website

This is what the request body looks like when i try it with the code

Doesnt look like the file is being chosen properly?

Also,

@"-----------------------------77748066757751
-----------------------------77748066757751--",

What do these parts mean?

How do you encode a file in your request? In bytes?

Here are examples on how to convert image to bytes - https://stackoverflow.com/questions/3801275/how-to-convert-image-to-byte-array
You may convert image like this instead of webclient:
Код:
byte[] mageBytes  = System.IO.File.ReadAllBytes(HttpContext.Current.Server.MapPath(path));

hi thanks, i already have converted the image into bytes but im not sure how to add it into the PUT request
I don't quite understand what problem you have...
This code converts the image to bytes automatically. all you need is just insert link to image at the beginning.
And put the link to website where to upload image in var response string.
Код:
string Url = "https://image_link";
using (var webClient = new System.Net.WebClient()) {
byte[] imageBytes = webClient.DownloadData(Url);

}

var response = ZennoPoster.HTTP.Request(ZennoLab.InterfacesLibrary.Enums.Http.HttpMethod.PUT,
"https://httpbin.org/put",
imageBytes[0],
"multipart/form-data",
"",
"",
ZennoLab.InterfacesLibrary.Enums.Http.ResponceType.BodyOnly
);
return response;

"https://httpbin.org/put",
imageBytes[0],
"multipart/form-data",
"",
"",
ZennoLab.InterfacesLibrary.Enums.Http.ResponceType.BodyOnly
);
return response;

i tried running that code but is is not runable,
this is what is says in the log "
Compile code of Error in action "CS0103" "The name 'imageBytes' does not exist in the current context". [Row: 9; Column: 1]
"

Код:
byte[] imageBytes;
string Url = "https://www.google.com/images/branding/googlelogo/1x/googlelogo_color_272x92dp.png";
using (var webClient = new System.Net.WebClient()) {
imageBytes = webClient.DownloadData(Url);
}

var response = ZennoPoster.HTTP.Request(ZennoLab.InterfacesLibrary.Enums.Http.HttpMethod.PUT,
"https://httpbin.org/put",
imageBytes[0],
"multipart/form-data",
"",
"",
ZennoLab.InterfacesLibrary.Enums.Http.ResponceType.BodyOnly
);
return response;
So i declared imageBytes outside but i am still geting error message:

Compile code of Error in action "CS1502" "The best overloaded method match for 'ZennoLab.CommandCenter.ZennoPoster.HTTP.Request(ZennoLab.InterfacesLibrary.Enums.Http.HttpMethod, string, string, string, string, string, ZennoLab.InterfacesLibrary.Enums.Http.ResponceType, int, string, string, bool, int, string[], string, bool, bool, ZennoLab.InterfacesLibrary.ProjectModel.ICookieContainer)' has some invalid arguments". [Row: 7; Column: 16]

Compile code of Error in action "CS1503" "Argument 3: cannot convert from 'byte' to 'string'". [Row: 9; Column: 1]

Something wrong with arguments in this method... - https://help.zennolab.com/en/v5/zennoposter/5.27.0.0/topic758.html
