I'm having a similar problem with FormatException being thrown. My code is simply: void Orders_OnSubmit() { DateTime CurrentTime = DateTime.Now; rtbAdd( "Submitted on " + CurrentTime.Date.ToString("MM/dd/yyyy") + " at " + CurrentTime.TimeOfDay.ToString("HH:mm:ss.ffffff") ); } void rtbAdd(String S) { DefaultDelegate del = delegate() { rtb.AppendText(S + "\n"); }; this.Invoke(del); } What's wrong here? Is this a threading issue? There's no need to explicitly access the Date and TimeOfDay properties of the DateTime instance. You can simplify your code like so: rtbAdd(String.Format("Submitted on

I have a little problem with ASP.NET and C#. This is my error code: An exception of type 'System.FormatException' occurred in mscorlib.dll but was not handled in >user code Additional information: Input string was not in a correct format. protected void Page_Load(object sender, EventArgs e) { if(this.IsPostBack == false) { Currency.Items.Add(new ListItem("Euro", "0.85")); Currency.Items.Add(new ListItem("Yen", "11.30")); Currency.Items.Add(new ListItem("PLN", "4.20")); Currency.Items.Add(new ListItem("GBP", "5.62")); } } protected void Convert_Click(object sender, EventArgs e) { decimal

I have created a program, and a extensive test of it, I'm getting a error that says "FormatException was unhandled, Input string was not in a correct format". The problem occurs when I leave either of the text boxes blank and press the 'Finished' button but it works fine if I enter anything below 0 or above 59 - which is the number range I want to allow. What could I do so I don't receive this error when the boxes are blank? This is my code behind 'btnFinished': private void btnFinished_Click(object sender, EventArgs e) { if (lstCyclists.SelectedIndex >= 0) { Cyclists currentCyc = (Cyclists

private void ReadUnitPrice() { Console.Write("Enter the unit gross price: "); unitPrice = double.Parse(Console.ReadLine()); } This should work, but I'm missing something obvious. Whenever I input a double it gives me the error: System.FormatException: Input string was not in a correct format. Note that 'unitPrice' is declared as a double. It could be that you're using wrong comma separation symbol or even made an other error whilst specifying double value. Anyway in such cases you must use Double.TryParse() method which is safe in terms of exception and allows specify format provider,

I have an existing function like this public int sFunc(string sCol , int iId) { string sSqlQuery = " select " + sCol + " from TableName where ID = " + iId ; // Executes query and returns value in column sCol } The table has four columns to store integer values and I am reading them separately using above function. Now I am converting it to Entity Framework . public int sFunc(string sCol , int iId) { return Convert.ToInt32(TableRepository.Entities.Where(x => x.ID == iId).Select(x => sCol ).FirstOrDefault()); } but the above function returns an error input string not in correct format because it

I'm trying to convert this string to double Convert.ToDouble("1.12"); and this is the output System.FormatException was unhandled. Should I do something like this? public static double ConvertToDouble(string ParseVersion) { double NewestVersion; try { NewestVersion = Convert.ToDouble(ParseVersion); } catch { ParseVersion = ParseVersion.Replace('.', ','); NewestVersion = Convert.ToDouble(ParseVersion); } return NewestVersion; } ConvertToDouble("1.12"); Or is there an easier solution? double.Parse will use the current culture by default. It sounds like you want the invariant culture: double d =
