Question

多个Dictionary<string, object>合并到一个Dictionary<string, object>？

static void Main(string[] args)        {            Dictionary<string, object> htmlAttributes = new Dictionary<string, object>();            //Dictionary<string, object> htmlAttributes1  = GetHtmlAttributes();            //foreach (KeyValuePair<string, object> k in GetHtmlAttributes())            //{            //    htmlAttributes.Add(k.Key, k.Value);            //}            htmlAttributes.Concat(GetHtmlAttributes());            Console.WriteLine();        }        private static Dictionary<string, object> GetHtmlAttributes()        {            Dictionary<string, object> htmlAttributes = new Dictionary<string, object>();                    htmlAttributes["required"] = "true";                    htmlAttributes["maxlength"] = "max.MaximumLength";                    htmlAttributes["minlength"] = "min.MinimumLength";                    htmlAttributes["rangemin"] = "range.Minimum";                    htmlAttributes["rangemax"] = "range.Maximum";                    htmlAttributes["regexp"] = "regexp.Pattern";            return htmlAttributes;        }htmlAttributes.Count() = 0   ?  谁能帮我解决这个问题么  ？  

Answer 1

var dicTest1=new Dictionary<string.Object>
{
{"test1","str1"},
{"test2",100}
};
var dicTest2=new Dictionary<string.Object>
{
{"test1","str1"},
{"test3","str3"},
{"test4", true},
{"test5",new DateTime()}
};
var dicTest3=dicTest1.Union(test2);
foreach(var keyValuePair in dicTest3)
{
Console.WriteLine("{0}:{1}",keyValuePair.Key,keyValuePair.Value);
}
Console.ReadLine();

注意要using System.Linq 的nameSpace
另外如果不想去重的话 就用
dicTest1.Concat(test2);
