大家好，今天要介绍的是和打包相关的API，之前讲过一篇文章是关于打包时候的注意事项，这里就不再介绍了，有需要的家人可以访问前一个文章：
C# Solidworks二次开发：Pack and Go打包时需要注意的地方，纯干货（可以节省大量查找资料时间）-CSDN博客
下面介绍相关API:
（1）第一个为AddExternalDocument，这个API的含义为将非solidworks文件添加到打包或是移动中，下面是官方的具体解释：
其输入参数值只有一个为要添加到打包和移动的非solidworks文件的路径和文件名的数组，返回值为bool类型，成功为true，失败为false。
下面是官方使用的例子：
This example shows how to add SOLIDWORKS, render reference, and non-SOLIDWORKS files to Pack and Go. This example also shows how to remove a non-SOLIDWORKS file from Pack and Go.
//-------------------------------------------
// Preconditions:
// 1. Verify that the specified assembly exists.
// 2. Create c:\PackAndGo.
// 3. Open the Immediate window.
//
// Postconditions:
// 1. Gets the names of SOLIDWORKS, render reference, and
// non-SOLIDWORKS files for Pack and Go.
// 2. Gets the the name of non-SOLIDWORKS file to remove.
// 3. Packs up SOLIDWORKS, render reference, and
// non-SOLIDWORKS files and copies them to c:\PackAndGo.
// 4. Examine c:\PackAndGo and the Immediate window.

（2）第二个为GetDocumentNames，这个API的含义为获取打包和移动所有文件的名称，下面是官方的具体解释：
其输入参数值只有一个为要添加到打包和移动的非solidworks文件的路径和文件名的数组，返回值为bool类型，成功为true，失败为false。和上面的一致。
(3)第三个为GetDocumentSaveToNames，这个API的含义为获取保存模型文档的路径和模型名，下面是官方的具体解释：
输入参数有两个，分别为：
PathNameList
包含保存模型文档的路径和文件名的字符串数组(参见备注)
DocumentStatusList
包含swPackAndGoDocumentStatus_e中定义的文档类型的数组
其对应的类型有三个：
本篇文章要介绍的API就是这些，我们下篇文章再见。
