I need to convert a string to a float....
-
Hi All,... I am reading into a rich text box a small number (0.385 to 0.457) which is read into a Rich Text Box as a string and my though was to use Text.ConvertTo(float) in the following way
Value_Extract = ((Convert.ToDecimal(rtbIncoming.Text));
Value_Extract is a float... This does not work compiles and Bang falls over when run, had look on Stack Overflow they seem to do in a similar way. Is this the correct way?? As VS helpfully tells me I need to cast a float as a decimal, decimal.tryparse??

I typically use float.TryParse(string, out float result); This returns true if successful and false if not. HTH

Are you sure it compiles?
Stringdoesn't have aConvertTomethod, and you can't pass theDecimaltype as an argument like that. Assuming the text is a valid number, thenConvert.ToSingle(rtdData.Text)should give you afloatback. OrConvert.ToDecimal(rtdData.Text)would give you adecimal, which you would then have to cast to store in afloatvariable. But these methods will throw an exception if the text is not a valid number. It would be better to usefloat.TryParse/decimal.TryParseso that you can notify the user if the value can't be parsed.

Okay, I will give that a go... It hasn't crashed yet!!

Hi, Thanks for that float.TryParse(), will I be able to get out as a floating point?..
Yes:
if (float.TryParse(myTextBox.Text, out float result))
{
Console.WriteLine(result);
