我在网站上搜索了类似的问题，似乎是一个32/64位的东西。但我仍然无法通过提供的方法来解决这个问题，例如在86/64目标平台之间切换
此处使用的软件是Visual Studio 2010和Matlab 2015a。我正在一个.m文件中测试一个非常简单的Matlab代码，该文件应该在图中绘制一条正弦曲线。此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)
它使用matlab NE构建器（我猜dll应该是64位）部署到名为testPlotN的dll，计划在c＃web项目中使用。我可以在c＃控制台应用程序上成功测试它（无论目标平台看起来是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();
}
}
}
然而，当我在c＃web应用程序中测试它时，使用主文件WebForm1.aspx
<%@ 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>
点击按钮时，按钮位于文件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();
}
}
}
当我在构建时使用默认选择任何cpu作为平台目标时，它会完美地显示页面
但是当我点击按钮时，错误就出现了

我花了两天时间来调试它。但是我甚至无法通过提供的方法来解决这个问题，例如在86/64目标平台和iis设置之间切换以启用32位应用程序。
任何线索都会非常感激！

通过启用我的案例解决了问题 将64位版本的IIS Express用于网站和项目
点击工具 - ＆gt;选项 - ＆gt;项目和解决方案 - ＆gt;网络项目
单击复选框以启用对网站和项目使用64位版本的IIS Express
答案 1 :(得分：0)
这可能与您正在使用的.NET版本以及内置DLL的内容有关。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>
此外，＆＃34;管理的管道＆＃34;应该在IIS中设置为Classic
答案 2 :(得分：0)
我的MatLab到.NET代码遇到了同样的问题。以下是两件事：
在Visual Studio中，在“项目属性”下 - ＆gt;构建，将平台目标设置为x64。这将使其适用于在IIS Express中进行测试。
部署时，只需将“启用32位应用程序”更改为“假”，确保将应用程序池设置为64位。
当我遇到这个问题时，这对我有用。
