核心主机

环境：Visual Studio 2022 + .NET6 + ArcGIS Pro SDK 3.0

1 初始化核心主机

using ArcGIS.Core.Data;
//必须引用ArcGIS.CoreHost.dll
using ArcGIS.Core.Hosting;

class Program {
    //[STAThread] 必须出现在应用程序入口点上
    [STAThread]
    static void Main(string[] args) 
    {
        //必须在构造任何 ArcGIS.Core 对象之前调用 Host.Initialize 
        try {
            Host.Initialize();
        }
        catch (Exception e) {
            //错误(缺少安装、没有许可证、64位不匹配等)
            Console.WriteLine(string.Format("Initialization failed: {0}",e.Message));
            return;
        }

        //执行到这，ArcGIS.Core已经初始化成功
        Geodatabase gdb = new Geodatabase(new FileGeodatabaseConnectionPath(new Uri(@"C:\Data\SDK\GDB\MySampleData.gdb")));
        IReadOnlyList<TableDefinition> definitions = gdb.GetDefinitions<FeatureClassDefinition>();

        foreach (var fdsDef in definitions) {
            Console.WriteLine(TableString(fdsDef as TableDefinition));
        }
        Console.Read();
    }

    private static string TableString(TableDefinition table) 
    {
        string alias = table.GetAliasName();
        string name = table.GetName();
        return string.Format("{0} ({1})", alias.Length > 0 ? alias : name, name);
    }
}
