Question

我需要修補一個字典的值與另一個添加新的密鑰。我需要保存新的密鑰並替換現有的密鑰才能完成補丁功能。必須有我無法訪問的現有映射。或者我應該寫什麼映射配置文件？

[Test] 
public void DictionaryMapping() 
{ 
    // Arrange 
    var write = new Dictionary<string, object> 
    { 
     { "Key1", 100 }, 
     { "Key2", true } 
    }; 
      var patch = new Dictionary<string, object> 
    { 
     { "Key2", false }, 
     { "Key3", "Additional"} 
    }; 

    // Act 
    Mapper.Map(patch, write); 

    // Assert 
    Assert.That(write["Key1"], Is.EqualTo(100)); 
    Assert.That(write["Key2"], Is.EqualTo(false)); 
    Assert.That(write["Key3"], Is.EqualTo("Additional")); 
}

您可以合併的字典是這樣的：

foreach(var keyValue in patch) 
    write[keyValue.Key] = keyValue.Value; 

這將覆蓋現有的和創造不存在的新的問題。
