关于c＃：“ MathWorks.MATLAB.NET.Utility.MWMCR”的类型初始值设定项引发了异常

The type initializer for 'MathWorks.MATLAB.NET.Utility.MWMCR' threw an exception

" MathWorks.MATLAB.NET.Utility.MWMCR"的类型初始值设定项引发了异常：

我从c＃调用，这是MatLab库编译器编译的DLL中的函数。

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 AddVidToDB;

namespace AddToDb
{
class Program
{
static void Main(string[] args)
{
Class1 obj = null;
// MWNumericArray input = null;
MWNumericArray output = null;
MWArray[] result = null;
MWArray input = null;

try
{
// Instantiate your component class.
obj = new Class1();

// Invoke your component.
string VidName ="080626439d8809181a1857685bdc645.mp4";
input[0] = VidName;
obj.AddVidToDB(input);
}
catch
{
throw;
}
}
}
}

当我运行代码时，它给出了一个例外：

"The type initializer for 'AddVidToDB.Class1' threw an exception.".
The inner exception says:"The type initializer for 'MathWorks.MATLAB.NET.Utility.MWMCR' threw an exception.".

堆栈跟踪说：

at AddVidToDB.Class1..ctor()
at AddToDb.Program.Main(String[] args) in d:\\MSc\\Project\\SurfSearchVid\\AddToDb\\AddToDb\\AddToDb\\Program.cs:line 40

那么我该如何解决呢？

您必须在计算机上安装运行时库才能调用MCR dll。
如果有，请检查PATH(环境变量)是否包含运行时路径。
您可以使用以下命令检查运行代码的用户是否具有正确的路径变量：

1	Environment.GetEnvironmentVariable("Path");

该变量必须包含以下内容：

C:\\Program Files\\MATLAB\\MATLAB Compiler Runtime\\v79\
untime\\{win32|win64};
