不打开文件的情况下获取文件的参考引用的API
是否存在一个API，在不打开文件的情况可以获取到他引用到的其它文件。比如，装配体某些文件获取到所有装配的子零部件。在SolidWorks中，类似的功能为ISldWorks::IGetDocumentDependencies2以及SwDMConfiguration8::GetReferencesInformation2.

可以用过ProgID启动天工CAD，置Interactive 和Visible属性为Flase。另一种做法是使用DesignManager，你这个情景比较推荐使用DesignManager来达到，下述为C#例程。
TGDesignManager.Application designApp = null;
TGDesignManager.Document doc = null;
TGDesignManager.LinkedDocuments linkedDocs = null;
TGDesignManager.Document linkedDoc = null;
TGDesignManager.PropertySets propertySets = null;
TGDesignManager.Property property = null;
public void GetBomInfoFromDesignMgr()
{
try
{
try
{
// 连接到已有的TGDesignManager，此时没有存在的实例会抛出异常
designApp = (TGDesignManager.Application)Marshal.GetActiveObject("DesignManager.Application");
}
catch
{
// 打开新的TGDesignManager
designApp = new TGDesignManager.Application();
designApp.Visible = 1;
}
// 打开想要获取BOM信息的装配文档
doc = (TGDesignManager.Document)designApp.OpenFileInDesignManager(selectedFilePath);
if (doc == null)
{
System.Windows.MessageBox.Show("文档正在被占用，请关闭文档后重试！");
}
linkedDocs = (TGDesignManager.LinkedDocuments)doc.LinkedDocuments;
propertySets = designApp.PropertySets as TGDesignManager.PropertySets;
//遍历装配文档下的子文件
for (long i = 1; i <= linkedDocs.Count; i++)
{
linkedDoc = (TGDesignManager.Document)linkedDocs;
// 获取子部件引用的数量
int docNumber = linkedDoc.Occurrences;
string fileName = linkedDoc.FullName;
propertySets.Open(fileName, true);
// 获取子部件BOM信息
TGDesignManager.Properties summaryProperties = (TGDesignManager.Properties)propertySets.Item["SummaryInformation"];
Dictionary<string, string> keyValuePairs = new Dictionary<string, string>();
// 遍历需要使用int，并且从0开始遍历
for (int j = 0; j < summaryProperties.Count; j++)
{
property = summaryProperties.Item as TGDesignManager.Property;
string name = property.Name;
var value = property.Value.ToString();
keyValuePairs.Add(name, value);
}
string bomInfo = DictionaryToString(keyValuePairs);
// 使用 MessageBox 显示字典内容
System.Windows.Forms.MessageBox.Show(bomInfo, "Dictionary Content", MessageBoxButtons.OK, MessageBoxIcon.Information);
// 获取文档自定义属性集 (这里需要改成对应的属性名称)
TGDesignManager.Properties customProperties = (TGDesignManager.Properties)propertySets.Item["Custom"];
// 也可以直接使用对应的属性名称索引获取值
//property = (TGDesignManager.Property)customProperties.Item["精度"];
//string name_1 = property.Name;
//string value_1 = property.Value.ToString();
}
designApp.Quit();
}
catch (Exception ex)
{
designApp.Quit();
}
}
