ASP .NET MVC Data type for image-CodePudding

I want to upload an image and then convert it to base64.

What data type should I choose ? I tried string but it gives me only the file name but not it's path.

public class TestModel
{
    public string Image { get; set; }
}

View:

@model Test.Models.TestModel

<form asp-action="Test" method="post">

        <div class="form-group">
            <input asp-for="Image" class="form-control" type="file" />
        </div>

        <div class="form-group">
            <input type="submit" value="Create" class="btn btn-primary" />
        </div>
    </form>

CodePudding user response：

You can Use IFormFile type to upload an image and then convert it to base64 in controller. Here is my code:

controller

  public IActionResult FileUpLoad(Models.TestModel model)
        {
            //convert it to base64
            var ms = new MemoryStream();
            model.Image.CopyTo(ms);
            var fileBytes = ms.ToArray();
            string result = Convert.ToBase64String(fileBytes);

            //......
            
            return RedirectToAction("Index");
        }

model

public class TestModel

    {
       
        public IFormFile Image { get; set; }
    }

view

<div>
    
    <form asp-controller="Home" asp-action="FileUpLoad" enctype="multipart/form-data" method="post">
       
        <input type="file" asp-for="Image" />
        <button type="submit">Submit</button>
    </form>
</div>

Upload an Image and then it can be converted to base64.
