ASP.NET中的ajax编辑器
本文关键字:编辑器 ajax 中的 NET ASP | 更新日期: 2023-09-27 18:26:42
我的页面中有一个Ajax编辑器:
<cc1:Editor ID="Editor1" runat="server" width="600px"/>
我想要的是将编辑器中的内容保存到我的数据库中。我试过了,但不起作用:
SqlCommand cmd = new SqlCommand(
"INSERT INTO titlu (descriere) Values(@descriere)",con);
cmd.Parameters.AddWithValue("@descriere", Editor1.Content);
我使用的是C#,它是一个ASP.Net web应用程序。。为什么我不能保存我的数据?
假设您的代码是这样的:
using (SqlConnection con = new ...)
{
SqlCommand cmd = new SqlCommand(
"INSERT INTO titlu (descriere) Values(@descriere)",con);
cmd.Parameters.AddWithValue("@descriere", Editor1.Content);
con.Open();
int affectedRows = cmd.ExecuteNonQuery();
}
那么cmd.ExecuteNonQuery()
行将抛出异常或返回受影响的行数——在您的情况下,它显然应该是1。
如果没有抛出异常,则将该值输入到数据库中-请确保Editor1.Content在此处访问时确实包含某些内容。还要确保你没有吞下例外。
您的代码不会显示在哪里执行SQL命令。如果执行命令什么您得到错误代码或异常吗?
参见此示例:
// Given command text and connection string, asynchronously execute
// the specified command against the connection. For this example,
// the code displays an indicator as it is working, verifying the
// asynchronous behavior.
using (SqlConnection connection =
new SqlConnection(connectionString))
{
try
{
int count = 0;
SqlCommand command = new SqlCommand(commandText, connection);
connection.Open();
IAsyncResult result = command.BeginExecuteNonQuery();
while (!result.IsCompleted)
{
Console.WriteLine("Waiting ({0})", count++);
// Wait for 1/10 second, so the counter
// does not consume all available resources
// on the main thread.
System.Threading.Thread.Sleep(100);
}
Console.WriteLine("Command complete. Affected {0} rows.",
command.EndExecuteNonQuery(result));
}
catch (SqlException ex)
{
Console.WriteLine("Error ({0}): {1}", ex.Number, ex.Message);
}
catch (InvalidOperationException ex)
{
Console.WriteLine("Error: {0}", ex.Message);
}
catch (Exception ex)
{
// You might want to pass these errors
// back out to the caller.
Console.WriteLine("Error: {0}", ex.Message);
}
}
