按键名从字典中删除键

Question

如果密钥是某个密钥,我正试图从我的字典中删除密钥.

parameterList是一个 dictionary<string,string>

parameterList.Remove(parameterList.Where(k => String.Compare(k.Key, "someKeyName") == 0)); 

Answer 1

这应该足够了:

parameterList.Remove(key);

Answer 2

只需按键删除:

parameterList.Remove("someKeyName");

去检查:

if (parameterList.Remove("someKeyName"))
{
    // key removed
}
else
{
    // dictionary doesn't contain the key
}
