如何導入Excel中的浮點數據到SQL Server與ASP.NET和C＃

Question

有人能解釋理論這個解決方案？我有簡單的代碼

var PersonID = worksheet.Cells[row, 1].Value;//คอลัมน์ 1 
var PersonName = worksheet.Cells[row, 2].Value;//int type in sql 
var PersonAge = worksheet.Cells[row, 3].Value;//char type 
var PersonCity = worksheet.Cells[row, 4].Value;//char type 
var PersonBugged = worksheet.Cells [row,5].Value;// Float type 

lsTestdbl.Add(new testdbl 
        { 
         id = PersonID == null ? "" : PersonID.ToString(), 
         name = PersonName == null ? "" : PersonName.ToString(), 
         age = PersonAge == null ? "" : PersonAge.ToString(), 
         city = PersonCity == null ? "" : PersonName.ToString(), 
         bugget = PersonBugged == null ?"" ; PersonBugged.ToString() 
        }); 
       } 

我已經可以導入char類型到SQL Server成功，但浮動和int我不知道該怎麼辦

Answer 1

應該轉換（解析）串所需類型。

int num = string.IsNullOrEmpty(PersonID) ? 0 : int.Parse(PersonID); 
double bugged = Convert.ToDouble(PersonBugged);
