Image1.Imageurl无法在Chrome中运行

Question

我需要Image1.Imageurl的帮助，我的代码只在IE中显示图像，但在Chrome中不显示。基本上我创建了通用处理程序来从数据库获取图像并将其传递给Image控制器。请告知我如何在Chrome和IE中使其运行。以下是我的代码，谢谢。

    Dim fileName As String = context.Request.QueryString("fn")

    Dim con As New SqlConnection(ConfigurationManager.ConnectionStrings("SQLConnection").ConnectionString)
    con.Open()
    Dim cmd As New SqlCommand("Select binary from ImageProcess where fileName = '" & fileName & "'", con)

    Dim dr As SqlDataReader = cmd.ExecuteReader
    dr.Read()

    Dim b64 As String = dr(0).ToString.Replace(" ", "+")
    Dim b() As Byte

    b = Convert.FromBase64String(b64)

    HttpContext.Current.Response.ContentType = "image/tiff"
    context.Response.BinaryWrite(b)
    con.Close()
    context.Response.[End]()
