如何在ASP.NET中使用GridView将日期绘制成一行？
我正在做一些表格开发工作，可以在其中将数据绘制到GridView中。这是一个12 x 31天的表格，该表格是将数据绘制到相应的天行和列中的每个价格。以一月份为例，需要在一月份的行上进行绘制，依此类推。下面的示例数据是我只需要在行上绘制的价格的确切数据。样本视图。
1 | 2 | 3 | 4 | 5 | 6 | 7 | 8 | 9 | 10 | and so on to 31
January 100|100|100|100|100|100|100|100|100|100 | and so on to 31
protected void Page_Load(object sender, EventArgs e)
{
string[] months = new string[]
{
"January", "February", "March", "April", "May", "June", "July", "August", "September", "October", "November", "December"
};
using (var reader = new StreamReader(@"C:\Projects\TestSample\TestSample\RenderJsonToView\prices.json"))

string jsonObject = reader.ReadToEnd();
var prices = JsonConvert.DeserializeObject<List<ComparePrice>>(jsonObject);

多年来，我已经使用该网站为一家酒店创建了一个系统，并且遇到了类似的情况，也许您有所收获，不同之处在于，就像您将房价包含在JSON文件中一样，我将其放在表格中，最后还有更多桌子，每间客房的价格是根据季节，提前天数，房间类型以及两者之间是否有假日来计算的。我有 var Q 的地方，您可以输入JSON查询，这是代码：
public DataTable DoGrid()
{
DateTimeFormatInfo dtfi = CultureInfo.GetCultureInfo("en-US").DateTimeFormat;
DataTable dt = new DataTable();
DataRow row;
dt.Columns.Add("No", typeof(int));
dt.Columns.Add("Year", typeof(string));
dt.Columns.Add("Month", typeof(string));
dt.Columns.Add("Date", typeof(string));
dt.Columns.Add("Occupation", typeof(string));
for(day = CalFrom.Date; day <= CalTo; day = day.AddDays(1))
{
var Q = db.Reservas.Where(c => c.CheckIn <= day && c.CheckOut > day && c.Cancelado == false);
string MyMonth = dtfi.GetMonthName(day.Month).ToString();
row = dt.NewRow();
row["No"] = dt.Rows.Count + 1;
row["Year"] = day.Year.ToString();
row["Month"] = MyMonth;
row["Date"] = day.ToString("dd/MM/yyyy");
row["Occupation"] = Q.Count();
dt.Rows.Add(row);
}
return dt;
}
public DateTime day { get; set; }
public DateTime CalFrom
{
get
{
return DpFrom.Value.Value;
}
}
public DateTime CalTo
{
get
{
return DpTo.Value.Value;
}
}
protected void Button1_Click(object sender, EventArgs e)
{
GridView1.DataSource = DoGrid();
GridView1.DataBind();
}
}
这是代码的结果
