How to pass generic method parameters in c#?

The way C# generic method parameters are passed is the same as regular method parameters. Here are some common ways of passing parameters:

  1. Passing parameters directly: directly passing the generic method’s parameters as actual arguments to the method.
public void MyGenericMethod<T>(T value)
{
    // 使用value参数
}

int intValue = 10;
string stringValue = "Hello";

MyGenericMethod(intValue); // 传递整数类型参数
MyGenericMethod(stringValue); // 传递字符串类型参数
  1. Passing parameters using variables: passing variables as actual arguments to a method.
public void MyGenericMethod<T>(T value)
{
    // 使用value参数
}

int intValue = 10;
string stringValue = "Hello";

var genericValue1 = intValue;
var genericValue2 = stringValue;

MyGenericMethod(genericValue1); // 传递泛型参数
MyGenericMethod(genericValue2); // 传递泛型参数
  1. Passing parameters by reference: passing reference type parameters as actual arguments to a method.
public void MyGenericMethod<T>(ref T value)
{
    // 使用value参数
}

int intValue = 10;
string stringValue = "Hello";

MyGenericMethod(ref intValue); // 传递整数类型参数的引用
MyGenericMethod(ref stringValue); // 传递字符串类型参数的引用

It is important to note that when passing reference type parameters, the ref keyword must be used to declare the parameter as a reference type.
