var name = assetField.AssetMetadata.Name; 
var htmlRender = assetField.RenderAsset();

3.5.2 How to retrieve metadata for the field type AssetLink

AssetlinkField assetLinkField = Sitecore.Context.Item.Fields["AssetLink"]; 
var name = assetLinkField.AssetMetadata.Name; 
var htmlRenderLink = assetLinkField.RenderAsset();

3.5.3 How to retrieve metadata for the field type AssetList

AssetlistField assetList = Sitecore.Context.Item.Fields["AssetList"];
if (assetList != null)
{
	foreach (var asset in assetList.Assets)
		{
		// To request the rendering html for the asset you call the
		// RenderAsset method. It returns an RenderFieldResult object
		var renderResultItem = asset.RenderAsset(); 
		var title = asset.AssetMetadata.Name;
		var id = asset.AssetMetadata.AssetId;
		var assetTypeId = asset.AssetMetadata.AssetTypeId;
		var assetTypeName = asset.AssetMetadata.AssetTypeName;
