Func<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, TResult> Delegate

Microsoft Silverlight will reach end of support after October 2021. Learn more.

Encapsulates a method that has 10 parameters and returns a value of the type specified by the TResult parameter.

Type Parameters

inT1
The type of the first parameter of the method that this delegate encapsulates.

This type parameter is contravariant. That is, you can use either the type you specified or any type that is less derived. For more information about covariance and contravariance, see 2678dc63-c7f9-4590-9ddc-0a4df684d42e.

inT2
The type of the second parameter of the method that this delegate encapsulates.

inT3
The type of the third parameter of the method that this delegate encapsulates.

inT4
The type of the fourth parameter of the method that this delegate encapsulates.

inT5
The type of the fifth parameter of the method that this delegate encapsulates.

inT6
The type of the sixth parameter of the method that this delegate encapsulates.

inT7
The type of the seventh parameter of the method that this delegate encapsulates.

inT8
The type of the eighth parameter of the method that this delegate encapsulates.

inT9
The type of the ninth parameter of the method that this delegate encapsulates.

inT10
The type of the tenth parameter of the method that this delegate encapsulates.

outTResult
The type of the return value of the method that this delegate encapsulates.

This type parameter is covariant. That is, you can use either the type you specified or any type that is more derived. For more information about covariance and contravariance, see 2678dc63-c7f9-4590-9ddc-0a4df684d42e.

Parameters

arg1
Type: T1
The first parameter of the method that this delegate encapsulates.

arg2
Type: T2
The second parameter of the method that this delegate encapsulates.

arg3
Type: T3
The third parameter of the method that this delegate encapsulates.

arg4
Type: T4
The fourth parameter of the method that this delegate encapsulates.

arg5
Type: T5
The fifth parameter of the method that this delegate encapsulates.

arg6
Type: T6
The sixth parameter of the method that this delegate encapsulates.

arg7
Type: T7
The seventh parameter of the method that this delegate encapsulates.

arg8
Type: T8
The eighth parameter of the method that this delegate encapsulates.

arg9
Type: T9
The ninth parameter of the method that this delegate encapsulates.

arg10
Type: T10
The tenth parameter of the method that this delegate encapsulates.

Return Value

Type: TResult
The return value of the method that this delegate encapsulates.

Remarks

You can use this delegate to represent a method that can be passed as a parameter without explicitly declaring a custom delegate. The encapsulated method must correspond to the method signature that is defined by this delegate. This means that the encapsulated method must have 10 parameters, each of which is passed to it by value, and that it must return a value.

Note:
To reference a method that has 10 parameters and returns void (or in Visual Basic, that is declared as a Sub rather than as a Function), use the generic Action<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10> delegate instead.

You can also use the Func<T1, T2, T3, T4, T5, T6, T7, T8, T9, T10, TResult> delegate with anonymous methods and lambda expressions.

The underlying type of a lambda expression is one of the generic Func delegates. This makes it possible to pass a lambda expression as a parameter without explicitly assigning it to a delegate.
