我想基於循環迭代向對象添加新屬性,這在.Net中可能嗎?我想這樣做的原因是我循環在Excel電子表格中的行,併爲每個成功讀取的行我想創建一個新的動態對象屬性。因此,當循環完成時,我可以簡單地將對象傳遞給方法並記錄所有記錄。是否有可能在.net 4.0中具有動態對象屬性
請參閱以下代碼至今:
protected void ReadData(string filePath, bool upload)
{
StringBuilder sb = new StringBuilder();
#region upload
if (upload == true) // CSV file upload chosen
{
using (CsvReader csv = new CsvReader(new StreamReader(filePath), true)) // Cache CSV file to memory
{
int fieldCount = csv.FieldCount; // Total number of fields per row
string[] headers = csv.GetFieldHeaders(); // Correct CSV headers stored in array
SortedList<int, string> errorList = new SortedList<int, string>(); // This list will contain error values
ORCData data = new ORCData();
bool errorFlag = false;
int errorCount = 0;
// Check if headers are correct first before reading data
if (headers[0] != "first name" || headers[1] != "last name" || headers[2] != "job title" || headers[3] != "email address" || headers[4] != "telephone number" || headers[5] != "company" || headers[6] != "research manager" || headers[7] != "user card number")
{
sb.Append("Headers are incorrect");
}
else
{
while (csv.ReadNextRecord())
try
{
//Check csv obj data for valid values
for (int i = 0; i < fieldCount; i++)
{
if (i == 0 || i == 1) // FirstName and LastName
{
if (Regex.IsMatch(csv[i].ToString(), "^[a-z]+$", RegexOptions.IgnoreCase) == false) //REGEX letters only min of 5 char max of 20
{
errorList.Add(errorCount, csv[i]);
errorCount += 1;
errorFlag = true;
string text = csv[i].ToString();
}
}
}
if (errorFlag == true)
{
sb.Append("<b>" + "Number of Error: " + errorCount + "</b>");
sb.Append("<ul>");
foreach (KeyValuePair<int, string> key in errorList)
{
sb.Append("<li>" + key.Value + "</li>");
}
}
else // All validation checks equaled to false. Create User
{
string message = ORCLdap.CreateUserAccount(rootLDAPPath, svcUsername, svcPassword, csv[0], csv[1], csv[2], csv[3], csv[4], csv[5], csv[7]);
// TODO: Add to object here
sb.Append(message);
//sb.Append("<b>New user data uploaded successfully</b>");
}
}// end of try
catch (Exception ex)
{
sb.Append(ex.ToString());
}
finally
{
lblMessage.Text = sb.ToString();
sb.Remove(0, sb.Length);
hdnRdoSelection.Value = "1";
}
}
}
}

我從來沒有嘗試過,所以我不知道我怎麼會接近,但任何幫助將是巨大的,做到這一點。謝謝。
我可以提出一個更簡單的例子嗎?目前尚不清楚您想添加動態屬性的位。坦率地說,一個'for(int i = 0; i <4; i ++)obj.SomeProp = value;'可能更清楚地表明意圖 –
