C# 比较dynamic和Dictionary性能

　　考虑到传递变参可能出现多个参数，以上测试不完全。
　　使用以下代码进行第二阶段实验：
public void InvokeDynamic()
{
var e = CallDynamic2(
new { Value1 = 0， Value2 = 0L， Value3 = 0f， Value4 = 0.0， Value5 = "test" });
int v1 = e.Value1;
long v2 = e.Value2;
float v3 = e.Value3;
double v4 = e.Value4;
string v5 = e.Value5;
}
public void InvokeDictionary()
{
var dict = new Dictionary<string， object>();
dict["Value1"] = 0;
dict["Value2"] = 0L;
dict["Value3"] = 0f;
dict["Value4"] = 0.0;
dict["Value5"] = "test";
dict = CallDictionary2(dict);
int v1 = (int)dict["Value1"];
long v2 = (long)dict["Value2"];
float v3 = (float)dict["Value3"];
double v4 = (double)dict["Value4"];
string v5 = (string)dict["Value5"];
}
private dynamic CallDynamic2(dynamic test)
{
int v1 = test.Value1;
long v2 = test.Value2;
float v3 = test.Value3;
double v4 = test.Value4;
string v5 = test.Value5;
v1++;
v2++;
v3++;
v4++;
v5 += "test";
return new { Value1 = v1， Value2 = v2， Value3 = v3， Value4 = v4， Value5 = v5 };
}
private Dictionary<string， object> CallDictionary2(
Dictionary<string， object> test)
{
int v1 = (int)test["Value1"];
long v2 = (long)test["Value2"];
float v3 = (float)test["Value3"];
double v4 = (double)test["Value4"];
string v5 = (string)test["Value5"];
v1++;
v2++;
v3++;
v4++;
v5 += "test";
var dict = new Dictionary<string， object>();
dict["Value1"] = v1;
dict["Value2"] = v2;
dict["Value3"] = v3;
dict["Value4"] = v4;
dict["Value5"] = v5;
return dict;
}
　　结果数据：
