Type.GetFields Method
.NET Framework 1.1
Gets the fields of the current Type.
Overload List
Returns all the public fields of the current Type.
Supported by the .NET Compact Framework.
[Visual Basic] Overloads Public Function GetFields() As FieldInfo()
[C#] public FieldInfo[] GetFields();
[C++] public: FieldInfo* GetFields() [];
[JScript] public function GetFields() : FieldInfo[];
When overridden in a derived class, searches for the fields defined for the current Type, using the specified binding constraints.
Supported by the .NET Compact Framework.
[Visual Basic] Overloads Public MustOverride Function GetFields(BindingFlags) As FieldInfo() Implements IReflect.GetFields
[C#] public abstract FieldInfo[] GetFields(BindingFlags);
[C++] public: virtual FieldInfo* GetFields(BindingFlags) [] = 0;
[JScript] public abstract function GetFields(BindingFlags) : FieldInfo[];
Example
The following example shows a use of the GetFields(BindingFlags) method.
