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描述的情况是特定基类应使用的扩展方法，其中具有与方法参数相关的通用参数。但是，扩展方法还应返回与所调用的特定后代相关的特定类型。

对于部分通用类型输入

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）; } 公共课程，这些公共课程 { // ... 执行 }

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