Represents a pointer to the method with two parameters and return type.
Inherited Members
Namespace: DotNext
Assembly: DotNext.dll
Syntax
public struct ValueFunc<T1, T2, TResult> : IValueDelegate<Func<T1, T2, TResult>>, ICallable<Func<T1, T2, TResult>>, ICallable, IConvertible<Func<T1, T2, TResult>>, ISupplier<Func<T1, T2, TResult>>, IEquatable<ValueFunc<T1, T2, TResult>>, ISupplier<T1, T2, TResult>
Type Parameters
Name | Description |
---|---|
T1 | The type of the first method parameter. |
T2 | The type of the second method parameter. |
TResult | The type of the return value of the method that this pointer encapsulates. |
Remarks
This method pointer is intended to call managed methods only.
Constructors
| Improve this Doc View SourceValueFunc(Func<T1, T2, TResult>, Boolean)
Initializes a new pointer based on extracted pointer from the delegate.
Declaration
public ValueFunc(Func<T1, T2, TResult> func, bool wrap = false)
Parameters
Type | Name | Description |
---|---|---|
Func<T1, T2, TResult> | func | The delegate representing method. |
Boolean | wrap | true to wrap |
Remarks
You can use this constructor to create value delegate once and cache it using static readonly
field
for subsequent calls.
Exceptions
Type | Condition |
---|---|
ArgumentNullException |
|
ValueFunc(MethodInfo)
Initializes a new pointer to the method.
Declaration
public ValueFunc(MethodInfo method)
Parameters
Type | Name | Description |
---|---|---|
MethodInfo | method | The method to convert into pointer. |
Remarks
This constructor causes heap allocations because Reflection is needed to check compatibility of method's signature with the delegate type.
Exceptions
Type | Condition |
---|---|
ArgumentNullException |
|
ArgumentException | Signature of |

ToDelegate()
Converts this pointer into Func<T1,T2,TResult>.
Declaration
public Func<T1, T2, TResult> ToDelegate()
Returns
Type | Description |
---|---|
Func<T1, T2, TResult> | The delegate created from this method pointer; or null if this pointer is zero. |
