C#调用webservice 提示方法没有任何重载采用"0"个参数

Question

c#webservicejava

Answer 1

MessageBox.Show(webservice.getPrice().ToString());
还有一个问题
你写的不是webserice吧

Answer 2

谢谢你的回复。
1.按照你说的试了，还是提示同样的错误。以下是getPrice的源码：
public void getPrice([System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] out int @return, [System.Xml.Serialization.XmlElementAttribute(Form=System.Xml.Schema.XmlSchemaForm.Unqualified)] [System.Xml.Serialization.XmlIgnoreAttribute()] out bool returnSpecified) {
            object[] results = this.Invoke("getPrice", new object[0]);
            @return = ((int)(results[0]));
            returnSpecified = ((bool)(results[1]));
        }2.为什么我写的不是webservice？？？

Answer 3

MessageBox.Show(webservice.getPrice(）);

Answer 4

首先没有看出这是webservice，你把 public int getPrice() { 改成 public string getPrice() { 试一试，webservice返回值就string就算了，用int没有意义

Answer 5

请问，这个为啥看不出是ws？？？VS2010中，我添加web引用，输入了wsdl，找到getGreeting和getPrice这两个方法，这还不是webservice吗？而且我添加完web引用后，会有一个Reference.cs文件生成，里面自动生成了getGreeting和getPrice这两个方法，这个可以改吗？我吧代码都贴在这：
