使用C#和ASP.NET写入数据并保存到SQL Server数据库
我对C#很陌生，我想做的是让用户在字段中输入数据，当他们点击submit时，将数据写入数据库。我真的被困住了，任何帮助都将不胜感激 这是我到目前为止所拥有的 我的标记：使用C#和ASP.NET写入数据并保存到SQL Server数据库,c#,asp.net,sql-server,C#,Asp.net,Sql Server,我对C#很陌生，我想做的是让用户在字段中输入数据，当他们点击submit时，将数据写入数据库。我真的被困住了，任何帮助都将不胜感激 这是我到目前为止所拥有的 我的标记： <%@ Page Language="C#" AutoEventWireup="true" CodeFile="Registration.aspx.cs" Inherits="subscribe_Registration" %> <!DOCTYPE html> <html xmlns="htt

提前感谢：）您应该在.cs代码中使用断点。这种程序中最常见的错误是数据库或.cs文件中字段的名称略有不同，因为该服务器的b'coz没有获得数据库中每个字段的值。这是一个错误
所以，正确使用断点并使用调试器来调试程序，以便找到出错的地方 您应该在.cs代码中使用断点。这种程序中最常见的错误是数据库或.cs文件中字段的名称略有不同，因为该服务器的b'coz没有获得数据库中每个字段的值。这是一个错误

你在坚持什么。。您甚至在哪里调用插入数据库的代码。。我看到了这个事件的代码<代码>按钮1\u单击您知道如何使用调试器吗。。？如果是这样，请在代码中设置一些断点，开始单步执行代码并计算变量等等……我想用按钮1_单击调用代码。创建存储过程或存储过程的最佳方法是什么？我对atm编程很陌生，只是想完成一项任务。编辑：很抱歉，只是阅读了你的全部评论，我会尝试使用调试器，但我只需要一些关于如何将数据保存到数据库的提示。一切正常，只是不确定从这里开始到哪里关于saing to database除了上面的评论之外，你还需要查看你的参数值。按照这种编码方式，您正在尝试将参数的值设置为文本框……您需要指定这些文本框的文本属性。如果这是我的代码，我会将插入逻辑从您的网页移到您的注册类中。您将收到作为参数的值，网页上的唯一代码将是调用Registration.Insertwhat You stack on。。您甚至在哪里调用插入数据库的代码。。我看到了这个事件的代码<代码>按钮1\u单击您知道如何使用调试器吗。。？如果是这样，请在代码中设置一些断点，开始单步执行代码并计算变量等等……我想用按钮1_单击调用代码。创建存储过程或存储过程的最佳方法是什么？我对atm编程很陌生，只是想完成一项任务。编辑：很抱歉，只是阅读了你的全部评论，我会尝试使用调试器，但我只需要一些关于如何将数据保存到数据库的提示。一切正常，只是不确定从这里开始到哪里关于saing to database除了上面的评论之外，你还需要查看你的参数值。按照这种编码方式，您正在尝试将参数的值设置为文本框……您需要指定这些文本框的文本属性。如果这是我的代码，我会将插入逻辑从您的网页移到您的注册类中。您将收到作为参数的值，网页上的唯一代码将是调用Registration.InsertThank You Denys，非常感谢您的帮助：）我收到一个代码错误“找不到类型或命名空间名称“Registration”因此，在代码隐藏文件中添加一个正确的
using，使用语句，以便它知道注册类所在的位置hh是的，这就是我忘记的。谢谢你的帮助。似乎做了我给你答案的把戏：）
