请using (ServiceHost host = new ServiceHost(typeof(HelloService.HelloService)))在下面的代码中帮助获得例外

例外:只有绝对URI可用作基址

WCF主机应用程序

    class Program
    {
        static void Main()
        {
            using (ServiceHost host = new ServiceHost(typeof(HelloService.HelloService)))
            {
                host.Open();
                Console.WriteLine("Service Started");
                Console.ReadLine();
            }
        }
    }

合同执行

    public class HelloService : IHelloService
    {
        public string GetMessage(string Name)
        {
            return "Hello" + Name;
        }
    }

合同

[ServiceContract]
    public interface IHelloService
    {
        [OperationContract]
        string GetMessage(string Name);
    }

App.Config中

<?xml version="1.0" encoding="utf-8" ?>
<configuration>
  <system.serviceModel>
    <services>
      <service name="HelloService.HelloService" behaviorConfiguration="mexBehaviour">
        <endpoint address="HelloService" binding="basicHttpBinding" contract="HelloService.IHelloService">
        </endpoint>
        <endpoint address="HelloService" binding="netTcpBinding" contract="HelloService.IHelloService"> …

任何人都可以告诉我,我没有使用系统名称空间,但字符串可用作字符串hello ="Hello"; 并且不会抛出任何编译时错误

但是,如果我写大写字符串,它就不可用.

sealed class SealedClass
{
    public void PrintSealed()
    {
        string hello = "Hello";
    }
}

为什么我们对以下情况有不同的输出:

object obj = "Int32";
string str1 = "Int32";
string str2 = typeof(int).Name;
Console.WriteLine(obj == str1); // true
Console.WriteLine(str1 == str2); // true
Console.WriteLine(obj == str2); // false !?

我得到参数计数不匹配异常:

获取未处理的异常:System.Reflection.TargetParameterCountException:参数计数不匹配.

码:

class Program
    {
        public static void Main()
        {
            ArrayList CustomerList = new ArrayList();
            CustomerList.Add("Robinson");
            CustomerList.Add("Pattison");
            CustomerList.Add("Todd");

            object[] obj = (object[])CustomerList.ToArray(typeof(object));
            Assembly executingAssembly = Assembly.GetExecutingAssembly();
            Type customerType = executingAssembly.GetType("LateBinding.Customer");
            object customerInstance = Activator.CreateInstance(customerType);
            MethodInfo method = customerType.GetMethod("printCustomerDetails");
            string customerObject = (string)method.Invoke(customerInstance, obj);
            Console.WriteLine("Value is : {0}", customerObject);
        }
    }
    public class Customer
    {
        public string printCustomerDetails(object[] parameters)
        {
            string CustomerName = "";
            foreach (object customer in parameters)
            {
                CustomerName = CustomerName + " " + customer;
            }
            return …
