将Dictionary<string，List<string>>转换为List<string，string>

Dictionary<string, List<string>> dictionary = new Dictionary<string, List<string>>();
// 假设已经给dictionary添加了一些键值对

List<string, string> resultList = new List<string, string>();

foreach (var kvp in dictionary)
{
    string key = kvp.Key;
    List<string> values = kvp.Value;

    foreach (string value in values)
    {
        resultList.Add(new KeyValuePair<string, string>(key, value));
    }
}

// 输出转换后的结果
foreach (var kvp in resultList)
{
    Console.WriteLine($"Key: {kvp.Key}, Value: {kvp.Value}");
}
