Any reason I should use Dictionary<string,string> instead of NameValueCollection?
(in C# / .NET Framework)
Option 1, using NameValueCollection:
//enter values:
NameValueCollection nvc = new NameValueCollection()
{
{"key1", "value1"},
{"key2", "value2"},
{"key3", "value3"}
};
// retrieve values:
foreach(string key in nvc.AllKeys)
{
string value = nvc[key];
// do something
}
Option 2, using Dictionary<string,string>...
//enter values:
Dictionary<string, string> dict = new Dictionary<string, string>()
{
{"key1", "value1"},
{"key2", "value2"},
{"key3", "value3"}
};
// retrieve values:
foreach (KeyValuePair<string, string> kvp in dict)
{
string key = kvp.Key;
string val = kvp.Value;
// do something
}
For these use cases, is there any advantage to use one versus the other? Any difference in performance, memory use, sort order, etc.?
