易语言引用VB.NET代码的DLL方法

首先创建一个VB.NET类库：

添加代码：

  Public Shared Function IsFileSigned(filePath As String) As Boolean
        Try
            Dim certificate As X509Certificate = X509Certificate.CreateFromSignedFile(filePath)
            Return True
        Catch ex As Exception
            Return False
        End Try
    End Function

然后右键-添加NuGet程序包-搜索：DllExport，然后进行引用。
安装完成之后，弹出的窗体中按下图来点击设置。

下面点击：全部重新加载

在代码顶部添加：
改变为：

<DllExport>
    Public Shared Function IsFileSigned(filePath As String) As Boolean
        Try
            Dim certificate As X509Certificate = X509Certificate.CreateFromSignedFile(filePath)
            Return True
        Catch ex As Exception
            Return False
        End Try
    End Function

然后在生成的同目录下找到X86目录，将DLL，放入易语言中，便可以引用。
