Collection always null when using [FromForm] attribute
For test I used the following arrayOfContent:
var arrayOfContent = [];arrayOfContent.push({ name: 'test', link: 'test.com' });arrayOfContent.push({ name: 'test2', link: 'test2.com' });And I used a for loop to append the array to the form data:
for (var i = 0; i < arrayOfContent.length; i++) { formData.append("Contents[" + i + "].Name", arrayOfContent[i].name); formData.append("Contents[" + i + "].Link", arrayOfContent[i].link);}And I in Visual Studio I can see that it can bind it:
You need to convert your array to JSON string in ajax submit code like this
const formData = new FormData();formData.append("File", myFile, "image.jpg")formData.append("Contents", JSON.stringify(arrayOfContent))Then deserialize in your controller
