php - Reassigning an array frees the memory used by it? -

-

There are a member variable array in my class, from time to time I have the array as the value of the second, floating array Reassign, such as: 

  $ temp = array (); $ Temp [] = new object (); $ Temp [] = new object (); $ Temp [] = new object (); ... etc $ $ - this- & gt; Item = $ temp;

So, can I have a memory leak? $ $ Value - $ temporarily awkward, or will they be free - $ temporarily by reallocating a new value, temporarily reassigning $ all items (item items)?

This will not cause the memory leak. $ Temp and $ the-> items are only references to the same array since PHP is a garbage collective language, the array will be removed (garbage collected) when there will be no reference to an array.

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...
