Can Partial Generic Type Inference Be Implemented in C#?

Overview

This article explores the challenges of implementing type inference in C#, focusing on the limitations and potential solutions for partial generic type inference.

The Problem

The use描述的情況是特定基類應使用的擴展方法，其中具有與方法參數相關的通用參數。但是，擴展方法還應返回與所調用的特定後代相關的特定類型。

對於部分通用類型輸入

This approach requires specifying both generic type arguments during invocation, which may not be desirable in all cases.

This approach involves splitting the operation into two functions:

public static thatwrapper { 返回新的whatwrapper （source）; } 公共課程，這些公共課程 { // ... 執行 }

public static TReg Parameter(this TReg p, string name, T value)
    where TReg : ParameterizedRegistrationBase
