在 WIA 中，ExecuteCommand 出现异常：

The method or operation is not implemented

代码：

WIA.CommonDialog dialog = new WIA.CommonDialog();
WIA.Device camera = dialog.ShowSelectDevice(WIA.WiaDeviceType.CameraDeviceType, false, true);
WIA.Item takenItem = camera.ExecuteCommand("{AF933CAC-ACAD-11D2-A093-00C04F72DC3C}");

有什么帮助……？

如果您遇到错误，您可能有不合适的相机。微软多年前取消了 WIA 库，最新的数码相机不支持 WIA 协议。以下是适用相机的简短列表：

佳能 IXUS 162,170,180 等最新数码相机不支持 WIA 协议。如果您正在寻找旧的“拍照”WIA 1.x/2.x 命令的替代品：{AF933CAC-ACAD-11D2-A093-00C04F72DC3C}，合适的方法是佳能 EOS 系列和佳能SDK 库。
