从Matlab部署dll的C＃.net Web应用程序

Question

I searched the similar problem on the website which seems a 32/64 bit thing. 我在网站上搜索了类似的问题，这似乎是32/64位的问题。 But I still can't figure it out even by the method provided such as toggling between 86/64 target platform 但是，即使通过提供的方法（例如在86/64目标平台之间切换），我仍然无法弄清楚

The software used here are Visual Studio 2010 and Matlab 2015a. 此处使用的软件是Visual Studio 2010和Matlab 2015a。 I am testing on a very simple Matlab code in a single .m file which is supposed to plot a sine curve in a figure. 我正在单个.m文件中的一个非常简单的Matlab代码上进行测试，该文件应该在图中绘制正弦曲线。 There is no input or output for this program: 该程序没有输入或输出：

function [] = testPlot()
x = 0:pi/100:2*pi;
y = sin(x);
%Create a line plot of the data.

figure % opens new figure window
plot(x,y)

It is deployed to dll named testPlotN using matlab NE builder (I guess the dll should be 64bit), which is planned to use in ac# web project. 使用Matlab NE Builder将其部署到名为testPlotN的dll中（我猜该dll应该为64bit），计划在ac＃Web项目中使用。 I can successfully test it on ac# console application (no matter the target platform is x86 or x64 seemingly) 我可以在ac＃控制台应用程序上成功测试它（无论目标平台看似是x86还是x64）

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using MathWorks.MATLAB.NET.Arrays;
using MathWorks.MATLAB.NET.Utility;
using testPlotN; //dll

namespace ConsoleApplication1

{
    class Program
    {
        static void Main(string[] args)
        {
            testP obj = new testP();//class from dll
            obj.testPlot();//matlab function
            Console.ReadKey();
        }
    }
}

However when I test it in ac# web application, with the main file WebForm1.aspx 但是，当我在ac＃Web应用程序中使用主文件WebForm1.aspx对其进行测试时

<%@ Page Language="C#" AutoEventWireup="true" CodeBehind="WebForm1.aspx.cs" Inherits="WebApplication2.WebForm1" %>

<!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "http://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">

<html xmlns="http://www.w3.org/1999/xhtml">
<head runat="server">
    <title></title>
</head>
<body>
    <form id="form1" runat="server">
    <div>

        hello my name is<asp:TextBox ID="TextBox1" runat="server" 
            ontextchanged="TextBox1_TextChanged"></asp:TextBox>
        <asp:Button ID="Button1" runat="server" onclick="Button1_Click" Text="OK" />
        <br />
        <br />
        <br />
        <asp:Label ID="lbloutput" runat="server"></asp:Label>
        <br />

    </div>
    </form>

</body>
</html>

And on click call for the button is in the file WebForm1.aspx.cs 在单击时，按钮调用位于文件WebForm1.aspx.cs中

using System;
using System.Collections.Generic;
using System.Linq;
using System.Web;
using System.Web.UI;
using System.Web.UI.WebControls;
using System.Threading.Tasks;
using MathWorks.MATLAB.NET.Arrays;
using MathWorks.MATLAB.NET.Utility;
using testPlotN;

namespace WebApplication2
{
    public partial class WebForm1 : System.Web.UI.Page
    {
        protected void Page_Load(object sender, EventArgs e)
        {

        }

        protected void TextBox1_TextChanged(object sender, EventArgs e)
        {

        }

        protected void Button1_Click(object sender, EventArgs e)
        {       
            testP obj = new testP();
            obj.testPlot();
        }
    }
}

When I use choose any cpu by default as platform target when building, it shows the page perfectly without any problem 当我在构建时使用默认情况下选择任何cpu作为平台目标时，它将完美显示页面，而没有任何问题

But when I click the button, the error came out 但是当我点击按钮时，错误出现了

I have spent two days to debug this. 我花了两天时间来调试它。 But I still can't figure it out even by the method provided such as toggling between 86/64 target platform and setting of iis to enable 32 bit application. 但是，即使通过所提供的方法（例如在86/64目标平台之间切换以及设置iis以启用32位应用程序），我仍然无法弄清楚。

Any clue would be much appreciated! 任何线索将不胜感激！

Answer 1

the problem was resolved in my case by enabling Use the 64 bit version of IIS Express for websites and projects 通过启用对网站和项目使用IIS Express的64位版本，就我而言，此问题已解决

click on tools --> Options --> Projects and Solutions --> Web Projects 单击工具->选项->项目和解决方案-> Web项目

Click on the check box to enable Use the 64 bit version of IIS Express for websites and projects 单击复选框以启用对网站和项目使用IIS Express的64位版本

Answer 2

This is likely to do with the version of .NET that you are using and what the DLL was built in. Try adding the following to the configuration file (Web.Config): 这可能与您所使用的.NET版本以及DLL的内置版本有关。请尝试将以下内容添加到配置文件（Web.Config）：

<configuration>
  <startup useLegacyV2RuntimeActivationPolicy="true">
    <supportedRuntime version="v4.0"/>
    <supportedRuntime version="v2.0.50727"/>
  </startup>
</configuration>

Also, the "Managed Pipeline" should be set to Classic in IIS 另外，“托管管道”应在IIS中设置为“经典”

Answer 3

I had this same problem with my MatLab to .NET code. 我的MatLab到.NET代码也遇到了同样的问题。 Here are two things to look at: 这里有两件事要看：

In Visual Studio, under Project Properties --> Build, set the Platform Target to x64. 在Visual Studio中，在“项目属性->生成”下，将“平台目标”设置为x64。 This will get it to work for testing in IIS Express. 这样可以使其在IIS Express中进行测试。
When you deploy, make sure your application pool is set to 64bit only by changing Enable 32-Bit Applications to False. 部署时，仅通过将“启用32位应用程序”更改为“假”来确保将应用程序池设置为64位。

This worked for me when I had this problem. 当我遇到这个问题时，这对我有用。
