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

/// <param name="server">数据库服务器名</param>
/// <param name="instance">SDE的端口，默认安装时"port:5151"</param>
/// <param name="user">SDE的用户名</param>
/// <param name="password">密码</param>
/// <param name="database">数据库的名字</param>
/// <param name="version">SDE的版本</param>
/// <returns></returns>
public IWorkspace OpenSdeWorkspaceByPropertySet(string server, string instance, string user, string password, string database, string version)
{
    IPropertySet Propset = new PropertySetClass();
    Propset.SetProperty("SERVER", server);
    Propset.SetProperty("INSTANCE", instance);
    Propset.SetProperty("USER", user);
    Propset.SetProperty("PASSWORD", password);
    Propset.SetProperty("DATABASE", password);
    Propset.SetProperty("VERSION", version);

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

2.通过连接字符串打开数据库

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

3.通过sde文件打开数据库
