获取OData连接信息
开发者有时可能需要从Excel文件中提取OData信息。Aspose.Cells for Python via .NET 提供了Workbook.data_mashup属性，该属性返回Excel文件中的DataMashup信息。这些信息由DataMashup类表示。DataMashup类提供了power_query_formulas属性，该属性返回PowerQueryFormulaCollction集合。通过PowerQueryFormulaCollction，可以访问PowerQueryFormula和PowerQueryFormulaItem。
以下代码片段演示了使用这些类来检索OData信息。
以下代码片段中使用的源文件，请参考附件。

| # For complete examples and data files, please go to https:# github.com/aspose-cells/Aspose.Cells-for-.NET | |
| # source directory | |
| SourceDir = RunExamples.Get_SourceDirectory() | |
| workbook = Workbook(SourceDir + "ODataSample.xlsx") | |
| PQFcoll = workbook.data_mashup.power_query_formulas | |
| for PQF in PQFcoll: | |
| print("Connection Name: " + PQF.name) | |
| PQFIcoll = PQF.power_query_formula_items | |
| for PQFI in PQFIcoll: | |
| print("Name: " + PQFI.name) | |
| print("Value: " + PQFI.value) |
