C# 按键名从字典中删除键

Remove a Key from Dictionary by key name

提问by PositiveGuy

I'm trying to remove a key from my dictionary if the key is a certain key.

如果键是某个键，我正在尝试从我的字典中删除一个键。

parameterList is a dictionary<string,string>

参数列表是一个 dictionary<string,string>

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

This should be enough:

这应该足够了：

parameterList.Remove(key);

Simply remove by key:

只需按键删除：

parameterList.Remove("someKeyName");

To check:

去检查：

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