Question

我试图存储2列并将其检索回来

column1 -> string
column2 - > UInt32

那么如何使用C＃在sqlite中存储和检索它们？

我想调用column1引用它的column2而没有任何问题。

Sample 1
select column1 from table1 where column2 = {this.UInt32_data}

提前感谢

使用此功能从 sqlite

中检索数据

public DataTable fillDataTable(string sqlCommand)
{
     DataTable dt = new DataTable();
     String config = "your connection string";
     using (var con = new SQLiteConnection { ConnectionString = config })
     {
          using (var command = new SQLiteCommand { Connection = con })
          {
               if (con.State == ConnectionState.Open)
                   con.Close();

               con.Open();
               command.CommandText = sqlCommand;

               dt.Load(command.ExecuteReader());

           }
           return dt;
     }
}
