static member ToSingle : 
        value:string -> float32

Parameters

value

A string that contains the number to convert.

Return Value

Type: System.Single

A single-precision floating-point number that is equivalent to the number in value, or 0 (zero) if value is null.

Using the ToSingle(String) method is equivalent to passing value to the Single.Parse(String) method. value is interpreted by using the formatting conventions of the current thread culture.

If you prefer not to handle an exception if the conversion fails, you can call the Single.TryParse method instead. It returns a Boolean value that indicates whether the conversion succeeded or failed.

The following example attempts to convert each element in an array of numeric strings to a Single value.
