Visual Studio 2022 新建WebService项目
创建之后启动运行
设置默认文档即可
经过上面的创建WebService已经创建完成，添加HelloWorld3方法，
[WebMethod]
public string HelloWorld3(int a, string b)
{
//var s = a + b;
return $"Hello World a+b={a + b}";
}
属性页面如下：
地址加上?wsdl----http://localhost:8012/WebService1.asmx?wsdl 可以查看具体方法，我们点开一个方法，查看具体调用方式，
http://localhost:8012/WebService1.asmx?op=HelloWorld3
下面使用 SOAP1.1 SOAP1.12 HTTP PSOT方式调用WebService，代码如下
cs
