使用.NET（C#或VB.NET）開發NX外部程序

 

1.如何不用將exe程序拷貝到UGII目錄下運行？

答：在調用NX Open命令函數前，將當前目錄移動到NX安裝目錄\UGII\,NX安裝目錄必須和環境變量UGII_BASE_DIR的值一致，否則報錯。可以使用如下代碼：

Dim instalDir As String = Environment.GetEnvironmentVariable("UGII_BASE_DIR")
System.IO.Directory.SetCurrentDirectory(instalDir)

 

2.我的外部程序很小，不想打包NX的.NET庫文件一起發布，而是使用用戶的庫文件，要怎樣做呢？

答：第一步，顯示項目所有文件，展開Application.myapp文件，再打開Application.Designer.vb文件，為MyApplication添加Startup事件回調函數，在里面添加如下代碼：

Dim ufdir As String = Environment.GetEnvironmentVariable("UGII_BASE_DIR")
 Reflection.Assembly.LoadFrom(IO.Path.Combine(ufdir, "\UGII\managed\NXOpen.dll"))
Reflection.Assembly.LoadFrom(IO.Path.Combine(ufdir, "\UGII\managed\NXOpen.UF.dll"))
Reflection.Assembly.LoadFrom(IO.Path.Combine(ufdir, "\UGII\managed\NXOpen.Utilities.dll"))

第二步，修改程序運行配置文件：你的exe程序文件名.config

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
    <runtime>
        <assemblyBinding xmlns="urn:schemas-microsoft-com:asm.v1">

                <assemblyIdentity name="NXOpen"  culture="neutral" publicKeyToken="null"/>

            </dependentAssembly>
        </assemblyBinding>
    </runtime>
</configuration>
