Dictionary<string,object> dic = new Dictionary <string, object> (); 就是创建了一个空集合，这个集合中的元素的键是string类型的，值是object类型的 dic. Add("@UserID", UserID); 自然就是往集合中增加了一个元素，元素的键是@UserID ，值是UserID Dictionary<string, object> dic = new...

如果函数返回值为常规意义上的值类型(Number、String、Boolean)时,new 函数将会返回一个该函数的实例对象,而如果函数返回一个引用类型(Object、Array、Function),虽然new函数与直接调用函数产生的结果等同,但是是两个不同的过程,一个是构造对象、一个是函数调用。 通过在 Test函数中返回不同类型的值进行测试,可以证实...
Today I'd like to write about Dictionary object which has been renewed in Small Basic 1.2.Ed Price told "Dictionary.com changed their API, so we lost use of that object in Small Basic 1.0 and 1.1. We finally got it fixed for 1.2." in comment of a last week blog post. So, ...
string FirstName { get; set; } public string LastName { get; set; } public int ID { get; set; } } } 2、C# 6.0中指定默认值的方法在C# 6.0及之后的版本中,字典初始化可以更加简洁地通过索引器语法进行,这使得在声明并初始化一个Dictionary时代码更加简洁明了。这种方法不仅适用于字典,还适用于...
var cppHelloWorldProgram = new Dictionary<int,string>{ [10] = "main() {", [20] = " printf(\"hello, world\")", [30] = "}" }; Field arguments in primary constructors are no longer part of C# 6.0. Both the binary numeric literal and the numeric separator (‘_’) within a nume...
You can use anobject or collection initializerwith thenewoperator to instantiate and initialize an object in one statement, as the following example shows: C# vardict =newDictionary<string,int> { ["first"] =10, ["second"] =20, ["third"] =30}; Console.WriteLine(string.Join("; ", dict...
