Answer 1

DataTable会帮你实现。请按照下面的代码

DataClassesDataContext db = new DataClassesDataContext(); 

protected DataTable GetDataSource() 
{ 
DataTable dt = new DataTable(); 

var questions = db.ExecuteQuery<string>("select question from quiz where quizid is 123").ToList(); 

// Header implementation 
int count = 0; 
foreach (var question in questions) 
{ 
    DataColumn dc = new DataColumn(question); 
    dt.Columns.Add(dc); 
    count++; 
} 

// Rows implementation here 
DataRow row = dt.NewRow(); 
... 
dt.Rows.Add(row); 

return dt; 
} 


protected void Page_Load(object sender, EventArgs e) 
{ 
GridView1.DataSource = GetDataSource(); 
GridView1.DataBind(); 
}
