從Matlab部署dll的C＃.net Web應用程序

[英]C# .net web application with dll deployed from matlab

 原文  2016-05-13 07:27:24  8   3    c#/ asp.net/ .net/ matlab/ dll

問題描述

我在網站上搜索了類似的問題，這似乎是32/64位的問題。 但是，即使通過提供的方法（例如在86/64目標平台之間切換），我仍然無法弄清楚

此處使用的軟件是Visual Studio 2010和Matlab 2015a。 我正在單個.m文件中的一個非常簡單的Matlab代碼上進行測試，該文件應該在圖中繪制正弦曲線。 該程序沒有輸入或輸出： 

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)

使用Matlab NE Builder將其部署到名為testPlotN的dll中（我猜該dll應該為64bit），計划在ac＃Web項目中使用。 我可以在ac＃控制台應用程序上成功測試它（無論目標平台看似是x86還是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();
        }
    }
}

但是，當我在ac＃Web應用程序中使用主文件WebForm1.aspx對其進行測試時 

<%@ 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>

在單擊時，按鈕調用位於文件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();
        }
    }
}

當我在構建時使用默認情況下選擇任何cpu作為平台目標時，它將完美顯示頁面，而沒有任何問題

但是當我點擊按鈕時，錯誤出現了

我花了兩天時間來調試它。 但是，即使通過所提供的方法（例如在86/64目標平台之間切換以及設置iis以啟用32位應用程序），我仍然無法弄清楚。

任何線索將不勝感激！

通過啟用對網站和項目使用IIS Express的64位版本，就我而言，此問題已解決

單擊工具->選項->項目和解決方案-> Web項目

單擊復選框以啟用對網站和項目使用IIS Express的64位版本

這可能與您所使用的.NET版本以及DLL的內置版本有關。請嘗試將以下內容添加到配置文件（Web.Config）： 

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

另外，“托管管道”應在IIS中設置為“經典”

我的MatLab到.NET代碼也遇到了同樣的問題。 這里有兩件事要看：

  1. 在Visual Studio中，在“項目屬性->生成”下，將“平台目標”設置為x64。 這樣可以使其在IIS Express中進行測試。

  2. 部署時，僅通過將“啟用32位應用程序”更改為“假”來確保將應用程序池設置為64位。

當我遇到這個問題時，這對我有用。
