Marshal.OffsetOf<T> Method (String)
[Supported in the .NET Framework 4.5.1 and later versions]
Returns the field offset of the unmanaged form of a specified managed class.
Assembly: mscorlib (in mscorlib.dll)
A managed value type or formatted reference type. You must apply the StructLayoutAttribute attribute to the class.
- Type: System.String
The name of the field in the T type.
Return ValueType: System.IntPtr
The offset, in bytes, for the fieldName parameter within the specified class that is declared by platform invoke.
provides the offset in terms of the unmanaged structure layout, which does not necessarily correspond to the offset of the managed structure layout. Marshaling the structure can transform the layout and alter the offset. The T generic type parameter can be a value type or a formatted reference type (with either a sequential or explicit layout). You can obtain the size of the entire layout by using the SizeOf<T>(T) method. For additional information, see Default Marshaling for Value Types.
Beginning with the .NET Framework version 2.0, OffsetOf may expose private fields.
