转自原文 ArcSDE：C#打开SDE数据库的几种方式总结

1.通过指定连接属性参数打开数据库

1. /// <param name="server">数据库服务器名</param>
2. /// <param name="instance">SDE的端口，默认安装时"port:5151"</param>
3. /// <param name="user">SDE的用户名</param>
4. /// <param name="password">密码</param>
5. /// <param name="database">数据库的名字</param>
6. /// <param name="version">SDE的版本</param>
7. /// <returns></returns>
8. public IWorkspace OpenSdeWorkspaceByPropertySet(string server, string instance, string user, string password, string database, string version)
9. {
10. IPropertySet Propset = new PropertySetClass();
11. Propset.SetProperty("SERVER", server);
12. Propset.SetProperty("INSTANCE", instance);
13. Propset.SetProperty("USER", user);
14. Propset.SetProperty("PASSWORD", password);
15. Propset.SetProperty("DATABASE", password);
16. Propset.SetProperty("VERSION", version);
17. IWorkspaceFactory workspaceFactory = new SdeWorkspaceFactoryClass();
18. return workspaceFactory.Open(Propset, 0);
19. }

2.通过连接字符串打开数据库

1. /// <param name="connectionString">连接字符串</param>
2. /// For example, "SERVER=Kona;DATABASE=sde;INSTANCE=5151;USER=Editor;PASSWORD=Editor;VERSION=sde.DEFAULT"
3. /// <returns></returns>
4. public IWorkspace OpenSdeWorkspaceByConnectionString(string connectionString)
5. {
6. IWorkspaceFactory2 workspaceFactory = new SdeWorkspaceFactoryClass();
7. return workspaceFactory.OpenFromString(connectionString, 0);
8. }

3.通过sde文件打开数据库

1. /// <param name="connectionFile">sde文件</param>
2. /// For example, "C:\\Data.sde"
3. /// <returns></returns>
4. public IWorkspace OpenSdeWorkspaceFromFile(string connectionFile)
5. {
6. IWorkspaceFactory workspaceFactory = new SdeWorkspaceFactoryClass();
7. return workspaceFactory.OpenFromFile(connectionFile, 0);
8. }
