c++ - Convert const char* string to NSString with length AND encoding -

-

I wonder which method would be better to convert the const char * string into NSString.
I found that there are some facts

  • [NSString stringWithCString: length:] There is a kind of boycott.
  • [NSString stringWithCString: encoding] can be used for my purpose

but I want to convert with length and encoding (because I have a UTF- 8 is OK for some non-ASCII characters by setting the encoding). any idea?

I think now

  1. Copy the other four and copy it using length std :: strncpy (ch1, ch2, len)
  2. Usage [NSString stringWithCString: encoding:]

But it does not work well.

If your const char * variable is named foo (and this is a Pointing to the redundant string), then just say 

  [NSString stringWithUTF8String: Foo]

Because UTF-8 is a superset of ASCII, it Will work that indicates foo for UTF-8 or ASCII. You can then go to full Unicode without any problem.

c# - TypeConverter in propertygrid only converts from string, not to -

-
When the property grid is reached, only the conversion mechanism (often called) is called "Foo!" Returns the property string in the grid when I click to edit I get an exception Type.oo. Object type can not be changed to type. (Not properly translated,) What is a clue from the convert format, why not? And the error indicates that it is trying to convert to a string, not from. I think that when I want to edit this object, it will have to be converted from foo to string, and when the editing ends. Public class FooTypeConverter: StringConverter {public override object ConvertFrom (ITypeDescriptorContext Reference, CultureInfo Culture, Object Value) {New Foo (string) value); } Convert the public override object (Type the ITE DiskText Contact Reference, CultureInfo Culture, Object Value, Type Type) {Return "Foo!"; } Public override bool CanConvertFrom (ITypeDescriptorContext reference, type source type) {back true; } Public Override Bull CanConvertTo (ITypeDescrip...
