ASP.NET与Sql Server（数据存储）

问题描述

限时删除！！

我正在使用此代码将数据存储到sql server中的表中。但它显示了一个错误：C＃代码在数据库中插入数据。



这是我的代码：

使用System.Data .SqlClient;





protected void Button1_Click（object sender，EventArgs e）

{

SqlConnection cnn = new SqlConnection（）;

cnn.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings [sqlconnection] .ConnectionString;

cnn.Open （）;

SqlCommand cmd = new SqlCommand（）;

cmd.CommandText =select * from TableName;

cmd.Connection = cnn;

SqlDataAdapter da = new SqlDataAdapter（）;

da.SelectCommand = cmd;

DataSet ds = new DataSet（）;

da.Fill（ds，TableName）;

SqlCommandBuilder cb = new SqlCommandBuilder（da）;

DataRow drow = ds.Tables [ TableName] .NewRow（）;

drow [id] = TextBox1.Text;

drow [Name] = TextBox2.Text;

drow [Designation] = TextBox3.Text;

drow [Mobile_No] = TextBox4.Text;

drow [地址] = TextBox5.Text;



ds.Tables [TableName] .Rows.Add（drow）;

da.Update（ds，TableName）;

string script = @ < script language =javascript>

alert（''信息已成功保存....... !!!!!。''）;

< / script> ;;;

Page.ClientScript.RegisterStartupScript（this.GetType（），myJScript1，脚本）;

}



//在web.config中

I am using this code to store data into a table in sql server. But it shows me an error:"C# code to insert data in database".

Here is my code:
using System.Data.SqlClient;


protected void Button1_Click(object sender, EventArgs e)
{
SqlConnection cnn = new SqlConnection();
cnn.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings["sqlconnection "].ConnectionString;
cnn.Open();
SqlCommand cmd = new SqlCommand();
cmd.CommandText = "select * from TableName";
cmd.Connection = cnn;
SqlDataAdapter da = new SqlDataAdapter();
da.SelectCommand = cmd;
DataSet ds = new DataSet();
da.Fill(ds, " TableName ");
SqlCommandBuilder cb = new SqlCommandBuilder(da);
DataRow drow = ds.Tables["TableName"].NewRow();
drow["id"] = TextBox1.Text;
drow["Name"] = TextBox2.Text;
drow["Designation"] = TextBox3.Text;
drow["Mobile_No"] = TextBox4.Text;
drow["Address"] = TextBox5.Text;

ds.Tables["TableName "].Rows.Add(drow);
da.Update(ds, " TableName ");
string script = @"<script language=""javascript"">
alert(''Information have been Saved Successfully.......!!!!!.'');
</script>;";
Page.ClientScript.RegisterStartupScript(this.GetType(), "myJScript1", script);
}

//In web.config

<connectionStrings>
<add name="sqlconnection" connectionString="Data Source=.\SQLEXPRESS;AttachDbFilename=|DataDirectory|\Database.mdf;Integrated Security=True;User Instance=True" providerName="System.Data.SqlClient"/>
  </connectionStrings>
