在C#中,KeyValuePair
以下是KeyValuePair
- 创建KeyValuePair
对象:
KeyValuePair<string, int> pair = new KeyValuePair<string, int>("Key", 123);
- 获取键和值:
string key = pair.Key;
int value = pair.Value;
- 更新键和值:
pair = new KeyValuePair<string, int>("NewKey", 456);
- 使用KeyValuePair
作为参数或返回值:
public KeyValuePair<string, int> GetKeyValuePair()
{
return new KeyValuePair<string, int>("Key", 123);
}
public void ProcessKeyValuePair(KeyValuePair<string, int> pair)
{
// 处理键值对
}
- 使用KeyValuePair
在字典中进行迭代:
Dictionary<string, int> dictionary = new Dictionary<string, int>();
// 添加键值对到字典
foreach (KeyValuePair<string, int> pair in dictionary)
{
string key = pair.Key;
int value = pair.Value;
// 处理键值对
}
总而言之,KeyValuePair
