我的尝试：

What I have tried:

 [Authorize]
        [HttpPost]        
        public FileResult CreateChart()
        {
 chart.ChartAreas.Add(chartArea);
            var ms = new MemoryStream();
            chart.SaveImage(ms);
            GlobalSettings.SessionInfo["HomeChart"] = ms.GetBuffer();
            return File(ms.GetBuffer(), @"image/png"); 
}

<img id="ItemPreview" src="" />

$.ajax({
                       type: "POST",
                       contentType: "image/png",
                       timeout: 10000,
                       url: '@ViewData["BaseUrl"]/Home/CreateChart',

                       success: function (data) {

                               try {
                                   var ImgSrc = data
                                   $('#ItemPreview').attr('src', "data:image/png;base64," + ImgSrc);

                               } catch (error) {
                               }


                       }
                   });

我尝试过：

What I have tried:

 [Authorize]
        [HttpPost]        
        public FileResult CreateChart()
        {
 chart.ChartAreas.Add(chartArea);
            var ms = new MemoryStream();
            chart.SaveImage(ms);
            GlobalSettings.SessionInfo["HomeChart"] = ms.GetBuffer();
            return File(ms.GetBuffer(), @"image/png"); 
}

<img id="ItemPreview" src="" />

.ajax（ {
类型：POST，
contentType：image / png，
超时：10000，
url：'@ ViewData [BaseUrl] / Home / CreateChart' ，

成功：函数（数据）{

尝试{
var ImgSrc = data

.ajax({ type: "POST", contentType: "image/png", timeout: 10000, url: '@ViewData["BaseUrl"]/Home/CreateChart', success: function (data) { try { var ImgSrc = data

（'＃ItemPreview' ）.attr（'src'，data：image / png; base64，+ ImgSrc）;

} catch（错误）{
}


}
}）;

('#ItemPreview').attr('src', "data:image/png;base64," + ImgSrc); } catch (error) { } } });
