Selenium 在C中使用硒测试材料应用#

我试图用C#selenium测试一个有角度的11材质UI应用程序。我发现量角器可以做到这一点，但在获取下拉列表和查找材质角度应用程序的绑定选项值等方面并没有太大帮助。 有图书馆可以帮我吗

下面是最终渲染材质选择/下拉列表

<mat-select _ngcontent-dtu-c317="" role="combobox" aria-autocomplete="none" aria-haspopup="true" id="ddlContractMonth" formcontrolname="ContractMonth" required="" class="mat-select ng-tns-c220-8 ng-tns-c111-7 mat-select-required mat-select-empty ng-pristine ng-invalid ng-star-inserted mat-select-invalid ng-touched" ng-reflect-id="ddlContractMonth" ng-reflect-required="" ng-reflect-name="ContractMonth" aria-labelledby="mat-form-field-label-5 mat-select-value-3" tabindex="0" aria-expanded="false" aria-required="true" aria-disabled="false" aria-invalid="true" aria-describedby="mat-error-0"><div cdk-overlay-origin="" class="mat-select-trigger ng-tns-c220-8"><div class="mat-select-value ng-tns-c220-8" ng-reflect-ng-switch="true" id="mat-select-value-3"><span class="mat-select-placeholder ng-tns-c220-8 ng-star-inserted">&nbsp;</span><!--bindings={
  "ng-reflect-ng-switch-case": "true"
}--><!--bindings={
  "ng-reflect-ng-switch-case": "false"
}--></div><div class="mat-select-arrow-wrapper ng-tns-c220-8">

选项在DOM中的不同位置呈现
