本文介绍了一种通过代码实现WMTS服务加载的方法，详细展示了如何使用IWMTSConnectionFactory和IWMTSConnection接口来获取并连接WMTS服务，同时提供了具体的C#代码示例。注意，该操作不应在子线程中执行，以避免出现错误。

代码

/// <summary>
/// 加载WMTS服务
/// </summary>
/// <param name="sUrl"></param>
/// <returns></returns>
public List<ILayer> GetWMTSLayer(string sUrl)
{
	var lstLayer = new List<ILayer>();
	try
	{
		IPropertySet pPropertySet = new PropertySetClass();
		pPropertySet.SetProperty("URL", sUrl);
		IWMTSConnectionFactory pWmtsConnectionFactory = new WMTSConnectionFactoryClass();
		IWMTSConnection pWmtsConnection = pWmtsConnectionFactory.Open(pPropertySet, 0, null);
		IWMTSServiceDescription pWmtsServiceDescription = pWmtsConnection as IWMTSServiceDescription;
		for (int i = 0; i < pWmtsServiceDescription.LayerDescriptionCount; i++)
		{
			IWMTSLayerDescription pWmtsLayerDescription = pWmtsServiceDescription.LayerDescription[i];
			IWMTSLayer pWmtsLayer = new WMTSLayerClass();

			IPropertySet pPropSet = new PropertySetClass();
			pPropSet.SetProperty("URL", sUrl);
			pPropSet.SetProperty("LayerName", pWmtsLayerDescription.Identifier);

			WMTSConnectionName connectionName = new WMTSConnectionNameClass
			{
				ConnectionProperties = pPropSet
			};
			if (pWmtsLayer.Connect((IName)connectionName))
			{
				lstLayer.Add(pWmtsLayer as ILayer);
			}
		}
	}
	catch (Exception ex)
	{
		Console.WriteLine(ex.Message);
	}
	return lstLayer;
}
