c# - 如何在 C# 中将键和值分配给另一个字典中的字典？

Question

我正在尝试为基于另一个字典的字典分配键和值，如下所示，我不清楚如何在 C# 中执行此操作，我在下面为其编写了伪代码？任何人都可以帮助如何在C#？

类:

public class BuildMetrics
{
    public Dictionary<string, string[]> BitSanity { get; set; }
}

代码:-

var metrics = new BuildMetrics();
Dictionary<int, int[]> bitSanityResults = new Dictionary<int,int[]>(); 

try
{
    bitSanityResults = bitDB.bit_sanity_results.Where(x => x.software_product_build_id == latestBuildProductBuildId)
                            .ToDictionary(x => x.test_suite_id, x => 
                             new int[] { x.pass_count, x.fail_count });
}
catch(System.ArgumentException e)
{
    Console.WriteLine(e);
}
//pseudocode
foreach (var item in bitSanityResults){
    metrics.BitSanity[key] = bitDB.test_suites.Where(x => x.id == item.Key)
                                              .Select(x => x.suite_name).FirstOrDefault();
    metrics.BitSanity[Value1] = item.Value1/item.Value2;
    metrics.BitSanity[Value2] = item.Value1 + item.Value2;

}

Answer 1

您应该能够简单地使用 Add() 方法。

foreach (var item in bitSanityResults)
{
  //It looks like you select a string here. Notice that your Dictionary needs int as key!!!
  int key = bitDB.test_suites.Where(x => x.id == item.Key).Select(x => x.suite_name).FirstOrDefault();

  metrics.Add(key, new[] {item.Value[0]/item.Value[1], item.Value[0]+item.Value[1] });
}

希望对您有所帮助。如果我误解了你的问题，请告诉我。

更新:

我添加了一些空检查来向您展示如何解决您的 NullReference 问题:

foreach (var item in bitSanityResults)
{
  //It looks like you select a string here. Notice that your Dictionary needs int as key!!!
  int key = bitDB.test_suites.Where(x => x.id == item.Key).Select(x => x.suite_name).FirstOrDefault();

  if (metrics != null &&
      item != null &&
      item.Value[0] != null &&
      item.Value[1] != null)
  {
     metrics.BitSanity.Add(key, new[] {Convert.ToString(item.Value[0]), Convert.ToString(item.Value[1])});
  }
}
