C＃Windows 8.1 /获取SQLite字符串查询结果作为变量

Question

如何获得此SQLite查询结果的变量结果？ 我需要在我的Windows 8.1应用程序中访问这个。

string queryDB = string.Format("Select * from ContryLookup"); 
var tempcountryLookUpData = connection.Execute(queryDB);

您需要参考SqliteDataReader

static void Main() 
{ 
    string cs = "URI=file:test.db"; 

    using(SqliteConnection con = new SqliteConnection(cs)) 
    { 
     con.Open(); 

     string stm = "Select * from ContryLookup"; 

     using (SqliteCommand cmd = new SqliteCommand(stm, con)) 
     { 
      using (SqliteDataReader rdr = cmd.ExecuteReader()) 
      { 
       while (rdr.Read()) 
       { 
        Console.WriteLine(rdr.GetInt32(0) + " " 
         + rdr.GetString(1) + " " + rdr.GetInt32(2)); 
       }   
      } 
     } 

     con.Close(); 
    } 
}

你有一个执行过程调用执行？ 执行所需操作的一种方法是使用ExecuteReader过程并将其返回给DataReader对象。然后使用for循环遍历数据：

string sql = "select * from table"; 
SQLiteCommand command = new SQLiteCommand(sql, m_dbConnection); 
SQLiteDataReader reader = command.ExecuteReader(); 
while (reader.Read()) 
     Console.WriteLine(reader["columnName"]);
