在数据库中插入数据集记录

Question

我需要将数据集记录（C＃）插入到MS Accessdatabase表中。我需要做批量插入记录。

我如何在C＃中做到这一点

Answer 1

检查在这个环节可能是对你有用。 将vb.net代码转换为c＃ 在获取sql数据后，您可以导入和导出到msaccess。

对于这种任务，可考虑使用data adapter抽象。随着Microsoft Access数据库，您可以使用OleDbDataAdapter执行如下例所示：

// Prerequisite: The data to be inserted is available in a DataTable/DataSet. 
var data = new DataTable(); 
data.Columns.Add("CompanyName", typeof(string)); 
data.Columns.Add("Phone", typeof(string)); 
data.Rows.Add("Foo", "12345678"); 
data.Rows.Add("Bar", "87654321"); 

// Now, open a database connection using the Microsoft.Jet.OLEDB provider. 
// The "using" statement ensures that the connection is closed no matter what. 
using (var connection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data source=Northwind.mdb")) 
{ 
    connection.Open(); 

    // Create an OleDbDataAdapter and provide it with an INSERT command. 
    var adapter = new OleDbDataAdapter(); 
    adapter.InsertCommand = new OleDbCommand("INSERT INTO Shippers (CompanyName, Phone) VALUES (@CompanyName , @Phone)", connection); 
    adapter.InsertCommand.Parameters.Add("CompanyName", OleDbType.VarChar, 40, "CompanyName"); 
    adapter.InsertCommand.Parameters.Add("Phone", OleDbType.VarChar, 24, "Phone"); 

    // Hit the big red button! 
    adapter.Update(data); 
} 

你可以这样做对其他品牌的数据库引擎，以及通过更换OleDbCommand，OleDbDataAdapter和OleDbConnection用合适的实现为您的数据库引擎。对于Microsoft SQL Server，请查找以Sql为前缀的类，例如。 SqlCommand。

public void insert_dataset(DataSet ds,string ret_table, string table, string fileds, ArrayList arr_data) 
    { 
     ArrayList arr_rec=new ArrayList(); 

     string[] str_fields = fileds.Split(','); 

     for (int i=0;i<ds.Tables[ret_table].Rows.Count;i++) 
     { 
      for (int j = 0; j < str_fields.Length; j++) 
      { 
       arr_rec.Add(ds.Tables[ret_table].Rows[i].ItemArray[j]); 
      } 

      insert_table(table, fileds, arr_rec); 

      arr_rec.Clear(); 
     } 


    } 
    public void insert_table(string table,string fileds,ArrayList arr_data) 
    { 
     string str_command, str_params; 

     string[] str_fields = fileds.Split(','); 

     for (int i = 0; i < str_fields.Length; i++) 
     { 
      str_fields[i] = "@" + str_fields[i].Trim(); 
     } 

     str_params = string.Join(",", str_fields); 

     str_command = "INSERT INTO " + table + "(" + fileds + ") values(" + str_params + ")"; 

     con = new OleDbConnection(); 
     //for sql 
     //con=new SqlConnection(); 

     con.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=" + frm_main.cur_directory + "\\db_temp1.mdb;Persist Security Info=True"; 
     //for sql 
     //con.ConnectionString="server=(local);trusted_connection=yes;database=telephon;"; 

     cmd = con.CreateCommand(); 
     //for sql 
     //cmd=new SqlCommand(); 
     cmd.Connection = con; 

     con.Open(); 

     cmd.CommandText =str_command; 

     // cmd.Parameters.AddWithValue("@ACagname", "2"); 
     for (int i = 0; i < arr_data.Count; i++) 
     { 
      cmd.Parameters.AddWithValue(str_fields[i],arr_data[i]); 
     } 

     cmd.ExecuteNonQuery(); 

     con.Close(); 

    }
