如何将以下代码转换为LINQ格式？

Question

代码：

foreach (var testType in projectData.TestTypes.OrderBy(it => it.TestName))
{
     var testList = new TestList
     {
          benchTestTypeName = testType.TestName,
          DataProvider = this.projectDataService.CurrentDataProvider,
          ProjectData = projectData
     };
     this.tabItems.Add(new TabItem { Header = testType.TestName, Content = testList });
}

如何将上述代码转换为LINQ格式？如果我们转换为Linq，执行时间(i.e)是否会有一点改进，执行时间是否可以减少一点？截至目前，15 TestTypes需要大约4到5秒。

尝试以下方法：

var items = projectData.TestTypes
                       .OrderBy(it => it.TestName)
                       .Select(testType=> new TestList
                       {
                           benchTestTypeName = testType.TestName,
                           DataProvider = this.projectDataService.CurrentDataProvider,
                           ProjectData = projectData
                       });

foreach(var item in items)
   tabItems.Add(new TabItem { Header = item.benchTestTypeName, Content = item });
