比较两个键值字典C＃

Question

我有两本词典

1有字典A（期望值）和字典B.

它们都是字典，我希望能够说，如果B.Keys包含来自A的键，则比较这两个值并返回true或false。

我怎么写这样的东西：

if (B.ContainsKey(A.Keys))
        {

        }

关键值示例：

Dictionary<Key, Value> B = {name, "valueb"; last, "smith"}
Dictionary<Key, Value> A = {name, "valuea"; last, "smith"; middle, "m"}

if (name == name) 
{
 if("valueb" == "valuea" )
{
 return false;
}
}

Answer 1

扫描一个字典并在第二个查找并比较如下：

var a = new Dictionary<TK,TV>();
var b = new Dictionary<TK,TV>();

var isEquals = a.All(x =>
{
    TV v;
    if (b.TryGetValue(x.Key, out v))
       return x.Value.Equals(v);

    return false;
});

UPD

isEquals = true;
foreach(x in a)
{
    TV v;
    if (b.TryGetValue(x.Key, out v))
       isEquals = isEquals && x.Value.Equals(v);
    else
    {
       isEquals = false;
       break;
    }

}
