--  请教 调用dll 具体得代码
用matlab  生成的dll  文件名 fcs2txt.dll 已经复制到foxtable目录下.
matlab定义如下 
function [fcsdat, fcshdr, fcsdatcomp] = fcs2txt(filename)
请问 在foxtable 中 调用的具体步骤 帮助中 代码看不大明白
<dllImport("kernel32. dll", CharSet:=CharSet. Ansi, CallinConvention:=CallingConvention. Cdecl)〉
Public Function fcs2txt(ByVal InString As String) As Integer 
End Function
标红的这段不知道怎么改

Dim iRetUSB As Integer
    
iRetUSB = fcs2txt("f:\\r.fcs")
是这样调用吗?
执行提示
fcs2txt是一个命名空间，不能用作表达式。
错误代码：iRetUSB=fcs2txt（"f:\\r.fcs"）

fcs2txt MATLAB .NET Assembly (.NET Component)

1. Prerequisites for Deployment 

Verify that version 9.5 (R2018b) of the MATLAB Runtime is installed.   
If not, you can run the MATLAB Runtime installer.
To find its location, enter
  
    >>mcrinstaller
      
at the MATLAB prompt.
NOTE: You will need administrator rights to run the MATLAB Runtime installer. 

Alternatively, download and install the Windows version of the MATLAB Runtime for R2018b 
from the following link on the MathWorks website:

    http://www.mathworks.com/products/compiler/mcr/index.html
   
For more information about the MATLAB Runtime and the MATLAB Runtime installer, see 
"Distribute Applications" in the MATLAB Compiler SDK documentation  
in the MathWorks Documentation Center.

2. Files to Deploy and Package

-fcs2txt.dll
   -contains the generated component using MWArray API. 
-fcs2txtNative.dll
   -contains the generated component using native API.
-This readme file
    Note: if end users are unable to download the MATLAB Runtime using the
    instructions in the previous section, include it when building your 
    component by clicking the "Runtime included in package" link in the
    Deployment Tool.

fcs2txt Assembly Description

 

This assembly was created using MATLAB .NET Assembly. The public class methods included in this assembly allow access to the MATLAB functions specified during compilation.

 

IMPORTANT: What you need to use this assembly successfully:

 

MATLAB Runtime

 

MATLAB Runtime is a collection of native libraries that are required to execute the MATLAB functions. Consequently, the MATLAB Runtime must be installed on any machine that runs a MATLAB .NET Assembly generated component. If you install MATLAB, MATLAB Compiler or MATLAB .NET Assembly, you have access to the MATLAB Runtime automatically.  Otherwise, you must install the MATLAB Runtime by running the MCRInstaller executable.  Note: This assembly is only compatible with version 9.5 of the MATLAB Runtime.

 

Please contact the provider of this assembly for specific details about the MATLAB Runtime.

 

 

MWArray.dll

 

This assembly, which can be found in <mcr_root>\\toolbox\\dotnetbuilder\\bin\\win64\\v4.0, provides classes that act as the bridge between your application and the MATLAB Runtime.  Note: The fcs2txt assembly, generated by MATLAB .NET Assembly, will only work with an MWArray assembly that was built against the same version of the MATLAB Runtime.

 

The MWArray class hierarchy provides methods to create and access the MATLAB data types used by the MATLAB Runtime.  All of the classes derive from the abstract MWArray class and each of the derived classes, with the exception of MWIndexArray which is also abstract, maps to a MATLAB data type.  The data conversion class hierarchy includes;  MWNumericArray, MWLogicalArray, MWCharArray, MWStructArray, and MWCellArray.   Each class has properties and methods that can be used to query various attributes of the class such as the number of dimensions, dimension size, element size, field names etc.  

 

These classes can be explicitly instantiated and used as arguments to the MATLAB .NET Assembly generated class methods.  Where applicable, a native .NET primitive or array type can also be used as an input parameter that will be implicitly converted to the appropriate MWArray type.

先试试：iRetUSB=fcs2txt.fcs2txt（"f:\\r.fcs"）

再试试

先去掉全局代码
1、把MWArray.dll、MWComUtil.dll和fcs2txt.dll 复制到Foxtable安装目录，并添加引用：http://www.foxtable.com/webhelp/topics/1936.htm

如果还是看不懂，请继续百度。不要问我，我也没看懂
