This API supports the .NET Framework infrastructure and is not intended to be used directly from your code.

This API is not CLS-compliant. The CLS-compliant alternative is SecureString.

Namespace:  System.Security
Assembly:  mscorlib (in mscorlib.dll)

In C#, this constructor is defined only in the context of unsafe code.

Windows 2000 Platform Note: SecureString is only supported on Windows 2000 Service Pack 3 and later.

The following example instantiates a new SecureString object by passing its constructor a pointer to a character array.

No code example is currently available or this language may not be supported.
