Points to a string containing the name of theCFileobject causing the exception. Remarks Don't use this constructor directly, but rather call the global functionAfxThrowFileException.

// Parameter name: length2 To correct the error, ensure that the value of the invalid argument is non-negative. You can do this by providing a valid value, as the following code fragment does. C# Copy int dimension1 = 10; int dimension2 = 10; Array arr = Array.CreateInstance(type...
You can also use a type converter to convert a value from its name, as shown in the next code example. C# Color c = (Color)TypeDescriptor.GetConverter(typeof(Color)).ConvertFromString("Red"); In the following code example, you can use a type converter to print out the set of standard...

If your class implements a class name syntax, but does not implement a prototype object syntax for a particular function, you can still call both syntaxes. For example, if you implement a staticzerosmethod only, you can call: zeros(...,'like',MyClass(...)) ...
