UpdateFeatures() public method

在指定的数据集中，更新一组要素。 参数 targetFeatures 是新要素列表，其要素 ID 与数据集中待更新的要素 ID 相同，根据 ID 查找到待更新的要素， 然后将原要素更新到新的要素。
public UpdateFeatures ( string datasourceName, string datasetName, List targetFeatures ) : EditResult
datasourceName string 数据源名称，必设参数。
datasetName string 数据源名称，必设参数。
targetFeatures List 新要素列表。其 ID 与要更新的要素 ID 相同，必设参数。
return EditResult
