如何将字节数组作为参数发送到 HTML.Action?

How to send byte array as paramater to HTML.Action?

我今天一直在处理图表,我想我终于找到了一种方法让这一切都起作用,但我遇到了一个我不知道如何解决的问题。

在我的控制器中创建我的图表:

    foreach (var m in model[0].HistoryValues)
    {

        var chart = new Chart(width: 300, height: 200)
        .AddSeries(
        chartType: "bar",
        xValue: new[] { "Server", "Db", "Tickets" },
        yValues: new[] { m.ServerPerformance, m.Databaseperformance, m.SoldTicketsLastUpdate })
        .GetBytes("png");

        m.Bytes = chart;

        //m.ChartFile = File(chart, "image/bytes");
    };

现在我想在视图中将它们显示为图像:

   @foreach (var m in Model[0].HistoryValues)
    {
        <img src="@Html.Action("getImage", "OverWatch", new { byte[] Mybytes= m.Bytes })" alt="Person Image" />
    }

但我得到:

Invalid anonymous type member declarator. Anonymous type members must be declared with a member assignment, simple name or member access.

getImage 方法:

public FileContentResult getImage(byte[] bytes)
{
   return new FileContentResult(bytes, "image/jpeg");
}

我该如何解决这个问题?

在匿名类型中,您不定义变量类型 byte[]。它根据 m.Bytes

的类型自行计算
@foreach (var m in Model[0].HistoryValues)
{
    <img src="@Html.Action("getImage", "OverWatch", new { Mybytes= m.Bytes })" alt="Person Image" />
}
