什麼我不知道（學習目的）：C＃，類[]運營商和分配/複製
DdrRam memXMP=new DdrRam();
memXMP.addType("overclock");
memXMP.addType("low profile");
memXMP["low profile"]="lp"; // just trying to change the type of a ram
memXMP["overlock"]="oc"; //
int tmp=memXMP["lp"]; // gets id integer number of "lp"
我學到了什麼/完成（成功）：
DdrRam ven = new DdrRam();
ven.addMemoryType("ddr4");
ven.addMemoryType("ddr5");
ven.addMemoryType("stacked dram");
Console.WriteLine("ddr4 memory type id={0}",ven["ddr4"]);
Console.WriteLine("ddr5 memory type id={0}" , ven["ddr5"]);
Console.WriteLine("stacked dram memory type id={0}" , ven["stacked dram"]);
// getter is working as intended,
//output is:
ddr4 memory type id=0
ddr5 memory type id=1
stacked dram memory type id=2
類是：
class DdrRam
{
List<string> memTypes;
public DdrRam()
{
memTypes=new List<string>();
}
public void addMemoryType(string memAdd)
{
memTypes.Add(memAdd);
}
public int this[string prf]
{
get { return memTypes.IndexOf(prf); }
// set { memTypes[memTypes.IndexOf(strVal)] = value; }
// ven["ddr5"] = "double data rate 5";
// cannot implicitly convert string to int
}
// public string this [string strVal]
// {
// set { memTypes[memTypes.IndexOf(strVal)] = value; }
// }
// this makes [] an ambiguous call so I cant use.
~DdrRam()
{
}
};
問題：如何重載=運算符，這樣我就可以使用[]賦值或複製了？
myClassInstanceNotAnArray["string index"]=someObject;
