C#将值从一个字典替换到另一个字典

Dictionary<string, int> sourceDict = new Dictionary<string, int>();

sourceDict.Add("key1", 10);
sourceDict.Add("key2", 20);
sourceDict.Add("key3", 30);

foreach (var kvp in sourceDict)
{
    // 在这里进行值的替换操作
}

if (targetDict.ContainsKey(kvp.Key))
{
    targetDict[kvp.Key] = kvp.Value;
}
