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.   
18.     IWorkspaceFactory workspaceFactory = new SdeWorkspaceFactoryClass();  
19.     return workspaceFactory.Open(Propset, 0);  
20. }  

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. }
