Syntax

Type Parameters

Name	Description
T	The type of the target that the pointer points to.

Remarks

PersistentPointerReadOnly<T> has the following characteristics:

• Non-nullableYou can access the pointer's target directly without checking for null.
• PersistentThe pointer's target outlives the pointer's initial scope. You can let the pointer escape the current scope and store it for later access. No guarantees are made about how long the target will remain valid or who owns it.
• Single objectThe pointer points to a single target. You can only access that target directly. You cannot perform pointer arithmetic with the pointer.
• Read-onlyYou can only read the pointer's target. You cannot modify it.
• TypedThe pointer points to a single target of type T.

You should never create instances of PersistentPointerReadOnly<T> using its parameterless constructors or default(PersistentPointerReadOnly<T>). Doing so will result in undefined behavior. Always use the FromRaw(T*), FromIntPtr(nint), or FromUIntPtr(nuint) methods to create instances of PersistentPointerReadOnly<T> pointers.

Constructors

Name	Description
PersistentPointerReadOnly()	Do not use. Do not create instances of non-nullable pointers using parameterless constructors or default values.

Properties

Name	Description
AsIntPtr	Gets an nint that represents the same memory address as the current pointer.
AsUIntPtr	Gets an nuint that represents the same memory address as the current pointer.
HasTarget	Gets a value indicating whether the current pointer is non-null.
Raw	Gets a raw pointer pointing to the same target as the current pointer.
Target	Gets a read-only reference to the target value the current pointer is pointing to.

Methods

Name	Description
Equals(NullableFunctionPointer)	Indicates whether the current object is equal to another object of the same type.
Equals(NullablePointerReadOnly)	Indicates whether the current object is equal to another object of the same type.
Equals(NullablePointerUninitialized)	Indicates whether the current object is equal to another object of the same type.
Equals(PersistentPointerReadOnly<T>)	Indicates whether the current object is equal to another object of the same type.
Equals(object?)	Indicates whether this instance and a specified object are equal.
FromIntPtr(nint)	Creates a PersistentPointerReadOnly<T> from a memory address given as a nint.
FromRaw(T*)	Creates a PersistentPointerReadOnly<T> from a raw pointer.
FromUIntPtr(nuint)	Creates a PersistentPointerReadOnly<T> from a memory address given as a nint.

ToString(IFormatProvider?)	Formats the value of the current instance using the specified format.
ToString(string?)	Formats the value of the current instance using the specified format.
ToString(string?, IFormatProvider?)	Formats the value of the current instance using the specified format.
TryFormat(Span<byte>, out int, IFormatProvider?)	Tries to format the value of the current instance as UTF-8 into the provided span of bytes.
