问题描述
分析器错误
描述：解析为此请求提供服务所需的资源时发生错误。请查看以下特定的解析错误详细信息并相应地修改源文件。
分析器错误消息：无法创建类型'JSONDemo.Service1'。
来源错误：
第1行：<％@ WebService 语言 = C＃ CodeBehind = Service1.asmx.cs < span class =code-attribute> 类 = JSONDemo.Service1 ％>
源文件：/Service1.asmx行：1
解决方案
使用下面的代码
public string InsertWebservice（int CountryId，string UserName，int IsActive）
{
int rowsInserted;
using（SqlConnection conn = new SqlConnection（conStr））
{
string sql = string.Format（@INSERT INTO [TestDB]。[dbo]。[Table_1]（[UserName] ，[CountryId]，[IsActive]）VALUES（{0}，'{1}'，{2}），UserName，CountryId，IsActive）;
SqlCommand cmd = new SqlCommand（）;
cmd.Connection = conn;
cmd.CommandText = sql;
cmd.CommandType = CommandType.Text;
conn.Open（）;
rowsInserted = cmd.ExecuteNonQuery（）;
conn.Close（）;
cmd = null;
}
返回string.Format（谢谢，{0}插入的行数！，rowsInserted）;
}
首先你需要在webservice中创建webmethod，如下所示
< pre lang =c＃> [WebMethod]
public string Inserttblval（ int CountryId， string UserName， int IsActive）
{
int rowsInserted;
SqlConnection conn = new SqlConnection（你的connectionstring）;
string sql = string .Format（ @ INSERT INTO [TestDB]。[dbo]。[Table_1]（[UserName]，[CountryId]，[IsActive]）VALUES（{0}，'{1 }'，{2}），UserName，CountryId，IsActive）;
SqlCommand cmd = new SqlCommand（）;
cmd.Connection = conn;
cmd.CommandText = sql;
cmd.CommandType = CommandType.Text;
conn.Open（）;
rowsInserted = cmd.ExecuteNonQuery（）;
conn.Close（）;
cmd = null ;
return string .Format（ 谢谢，{0}插入的行数！，rowsInserted）;
}
下一页在aspx页面添加以下代码
< head runat = 服务器 >
< title > < / title >
< script type = text / javascript src = http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js < span class =code-keyword>> < / script >
< script type = text / javascript src = http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/jquery-ui.min.js > < / script >
< script type = text / javascript >
（function（）{
Parser Error
Description: An error occurred during the parsing of a resource required to service this request. Please review the following specific parse error details and modify your source file appropriately.
Parser Error Message: Could not create type 'JSONDemo.Service1'.
Source Error:
Line 1: <%@ WebService Language="C#" CodeBehind="Service1.asmx.cs" Class="JSONDemo.Service1" %>
Source File: /Service1.asmx Line: 1 解决方案
use below code
public string InsertWebservice(int CountryId, string UserName, int IsActive) { int rowsInserted; using (SqlConnection conn = new SqlConnection(conStr)) { string sql = string.Format(@"INSERT INTO [TestDB].[dbo].[Table_1] ([UserName],[CountryId],[IsActive]) VALUES ({0},'{1}',{2})", UserName, CountryId, IsActive); SqlCommand cmd = new SqlCommand(); cmd.Connection = conn; cmd.CommandText = sql; cmd.CommandType = CommandType.Text; conn.Open(); rowsInserted = cmd.ExecuteNonQuery(); conn.Close(); cmd = null; } return string.Format("Thank you, {0} number of rows inserted!", rowsInserted); }
first you need to create webmethod in webservice like below
[WebMethod] public string Inserttblval(int CountryId, string UserName, int IsActive) { int rowsInserted; SqlConnection conn = new SqlConnection(your connectionstring); string sql = string.Format(@"INSERT INTO [TestDB].[dbo].[Table_1] ([UserName],[CountryId],[IsActive]) VALUES ({0},'{1}',{2})", UserName, CountryId, IsActive); SqlCommand cmd = new SqlCommand(); cmd.Connection = conn; cmd.CommandText = sql; cmd.CommandType = CommandType.Text; conn.Open(); rowsInserted = cmd.ExecuteNonQuery(); conn.Close(); cmd = null; return string.Format("Thank you, {0} number of rows inserted!", rowsInserted); }
next in aspx page add below code
<head runat="server"> <title></title> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jquery/1.4.2/jquery.min.js"></script> <script type="text/javascript" src="http://ajax.googleapis.com/ajax/libs/jqueryui/1.8.1/jquery-ui.min.js"></script> <script type="text/javascript">
(function () {
