Marshal.PtrToStringUni Method (IntPtr)
Allocates a managed String and copies all characters up to the first null character from an unmanaged Unicode string into it.
Assembly: mscorlib (in mscorlib.dll)
<SecurityCriticalAttribute> Public Shared Function PtrToStringUni ( ptr As IntPtr ) As String
The address of the first character of the unmanaged string.
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 for use 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.
requires full trust for the immediate caller. This member cannot be used by partially trusted or transparent code.
