Marshal.PtrToStringUni Method (IntPtr, Int32)
Allocates a managed String and copies a specified number of characters from an unmanaged Unicode string into it.
Assembly: mscorlib (in mscorlib.dll)
- Type: System.IntPtr
The address of the first character of the unmanaged string.
- Type: System.Int32
The number of Unicode characters to copy.
Return ValueType: System.String
A managed string that holds a copy of the unmanaged string if the value of the ptr parameter is not null; otherwise, this method returns null.
PtrToStringUni is useful for custom marshaling or when mixing managed and unmanaged code. Because this method creates a copy of the unmanaged string's contents, you must free the original string as appropriate. This method provides the opposite functionality of the Marshal.StringToCoTaskMemUni and Marshal.StringToHGlobalUni methods.
