导致这种情况的原因是什么？
Error System.InvalidOperationException: UpdateProject Web Service method name is not valid.

==================================
正在使用JSON请求：
var jsonStr = Ext.encode({ 'project_id': 'a', 'project_number': 'b', 'project_name': 'c' });
Ext.Ajax.request({
url: 'http://localhost/Controls/ProjectList/ProjectListService.asmx/SaveProject',
method: 'POST',
jsonData: jsonStr,
success : function(response){
alert(response.responseText);
},
failure : function(response){
alert("Error " + response.responseText);
}
});
网络方法（目前为止）：
（参见上面的项目对象）
[WebMethod]
[ScriptMethod(ResponseFormat = ResponseFormat.Json, UseHttpGet = false, XmlSerializeString = false)]
public string SaveProject()
{
return "success";
}
================================
改变了两件事。为我的Web服务添加了“Project”类型的“project”参数。然后将Project对象属性放在我的“jsonData”对象中的该对象中。
正在使用JSON请求：
//var jsonStr = Ext.encode({ 'project_id': 'a', 'project_number': 'b', 'project_name': 'c' });
var jsonDataObject = { 'project': { 'project_id: '4', 'project_number': '004', 'project_name': 'project 4' } };
Ext.Ajax.request({
url: 'http://localhost/Controls/ProjectList/ProjectListService.asmx/SaveProject',
method: 'POST',
jsonData: jsonDataObject,
success : function(response){
alert(response.responseText);
},
failure : function(response){
alert("Error " + response.responseText);
}
});
网络方法（目前为止）：

public string SaveProject(Project project)

答案 0 :(得分：2)
看起来序列化程序认为您不能将对象作为JSON节点的属性。
尝试一些事情：
params: { project_id: 'a', project_number: 'b', project_name: 'c' }
