如何将datagridview中的导入excel保存到数据库C＃

如何将导入的数据从datagridview中的excel保存到C＃中的数据库我已经保存logging并导出到excel表单，它与数据ID一起导出，现在我已经从excel重新导入到datagridview。 现在我想将数据保存到数据库。

重要知道：

数据库名称“Records.sdf”使用SQL Compact 3.5 DataGridViewName是RecordsDataGridView。

我正在使用下面的代码，但它不工作。

public void SaveData() { // Save the data. SqlCeConnection conn = new SqlCeConnection( @"Data Source=|DataDirectory|\Records.sdf;Persist Security Info=False"); SqlCeCommand com; string str; conn.Open(); for (int index = 0; index < RecordsDataGridView.Rows.Count - 1; index++) { str = @"Insert Into OutgoingChequeRecords(ID,BankName,Date,AccountNo, Chequebook, ChequeNo, Payee, Amount, Remarks) Values(" + RecordsDataGridView.Rows[index].Cells[0].Value.ToString() + ", '" + RecordsDataGridView.Rows[index].Cells[1].Value.ToString() + "'," + RecordsDataGridView.Rows[index].Cells[2].Value.ToString() + "," + RecordsDataGridView.Rows[index].Cells[3].Value.ToString() + "," + RecordsDataGridView.Rows[index].Cells[4].Value.ToString() + "," + RecordsDataGridView.Rows[index].Cells[5].Value.ToString() + "," + RecordsDataGridView.Rows[index].Cells[6].Value.ToString() + "," + RecordsDataGridView.Rows[index].Cells[7].Value.ToString() + "," + RecordsDataGridView.Rows[index].Cells[8].Value.ToString() + ")"; com = new SqlCeCommand(str, conn); com.ExecuteNonQuery(); } conn.Close(); } 

错误接收 列名无效，列名=现金

Answer 1

试试这个查询string

  str = @"Insert Into OutgoingChequeRecords(ID,BankName,Date,AccountNo, Chequebook, ChequeNo, Payee, Amount, Remarks) Values(" + RecordsDataGridView.Rows[index].Cells[0].Value.ToString() + ",'"+ RecordsDataGridView.Rows[index].Cells[1].Value.ToString() + "'," + RecordsDataGridView.Rows[index].Cells[2].Value.ToString() + ",'" + RecordsDataGridView.Rows[index].Cells[3].Value.ToString() + "','" + RecordsDataGridView.Rows[index].Cells[4].Value.ToString() + "','" + RecordsDataGridView.Rows[index].Cells[5].Value.ToString() + "','" + RecordsDataGridView.Rows[index].Cells[6].Value.ToString() + "','" + RecordsDataGridView.Rows[index].Cells[7].Value.ToString() + "','" + RecordsDataGridView.Rows[index].Cells[8].Value.ToString() + "')"; 

Answer 2

你应该传递用单引号括起来的varchar字段。

  var str = @"Insert Into OutgoingChequeRecords(ID,BankName,Date,AccountNo, Chequebook, ChequeNo, Payee, Amount, Remarks) Values(" + RecordsDataGridView.Rows[index].Cells[0].Value.ToString() + ", '" + RecordsDataGridView.Rows[index].Cells[1].Value.ToString() + "'," + RecordsDataGridView.Rows[index].Cells[2].Value.ToString() + "," + RecordsDataGridView.Rows[index].Cells[3].Value.ToString() + "," + RecordsDataGridView.Rows[index].Cells[4].Value.ToString() + "," + RecordsDataGridView.Rows[index].Cells[5].Value.ToString() + "," + "'" + RecordsDataGridView.Rows[index].Cells[6].Value.ToString() + "'" + "," + RecordsDataGridView.Rows[index].Cells[7].Value.ToString() + "," + "'" + dataGridView1.Rows[index].Cells[8].Value.ToString() + "'" + ")"; 

Answer 3

有几种方法可以做到这一点。

这是一种方法。

 private void save_btn_Click(object sender, EventArgs e) { sAdapter.Update(sTable); dataGridView1.ReadOnly = true; save_btn.Enabled = false; new_btn.Enabled = true; delete_btn.Enabled = true; } 

http://csharp.net-informations.com/datagridview/csharp-datagridview-database-operations.htm

你也可以做到这一点。

 string StrQuery; try { using (SqlConnection conn = new SqlConnection(ConnString)) { using (SqlCommand comm = new SqlCommand()) { comm.Connection = conn; conn.Open(); for(int i=0; i< dataGridView1.Rows.Count;i++) { StrQuery= @"INSERT INTO tableName VALUES (" + dataGridView1.Rows[i].Cells["ColumnName"].Text+", " + dataGridView1.Rows[i].Cells["ColumnName"].Text+");"; comm.CommandText = StrQuery; comm.ExecuteNonQuery(); } } } } 

这样的事情也会起作用。

 private void buttonSave_Click_1(object sender, EventArgs e) // save to invoice { SqlConnection con = new SqlConnection(MyConnectionString); string SqlCmdText = "INSERT INTO invoice (p_code, p_name, p_category, p_price) " + VALUES (@code, @name, @category, @price)"; SqlCommand sc = new SqlCommand(SqlCmdText, con); con.Open(); foreach (DataRow row in MyTable.Rows) { sc.Parameters.Clear(); sc.Parameters.AddWithValue("@code", row["p_code"]); sc.Parameters.AddWithValue("@name", row["p_name"]); sc.Parameters.AddWithValue("@category", row["p_category"]); sc.Parameters.AddWithValue("@price", row["p_price"]); sc.ExecuteNonQuery(); } con.Close(); }
