是否可以在我的組件中放置多個 InvokeAsync？因為我的組件有時會回傳一些小東西，如果我為每個組件創建不同的檔案和類，就很難管理它們
public async Task<IViewComponentResult> InvokeAsync(
int maxPriority, bool isDone)
{
string MyView = "Default";
// If asking for all completed tasks, render with the "PVC" view.
if (maxPriority > 3 && isDone == true)
{
MyView = "PVC";
}
var items = await GetItemsAsync(maxPriority, isDone);
return View(MyView, items);
}
public async Task<IViewComponentResult> myInvokeAsync2(
int maxPriority, bool isDone)
{
string MyView = "Default";
// If asking for all completed tasks, render with the "PVC" view.
if (maxPriority > 3 && isDone == true)
{
MyView = "PVC";
}
var items = await GetItemsAsync(maxPriority, isDone);
return View(MyView, items);
}
以及如何稱呼它？
@await Component.InvokeAsync("PriorityList", new { maxPriority = 4, isDone = true })
@await Component.myInvokeAsync2("PriorityList", new { maxPriority = 4, isDone = true })

不，一個組件只能有一種InvokeAsync方法：
在 ASP.NET Core 中查看組件 | 微軟檔案
但是，如果您要呼叫的所有方法都采用相同的引數集，您可以傳入一個額外的引數來指定要呼叫的方法。
public Task<IViewComponentResult> InvokeAsync(
int method, int maxPriority, bool isDone) => method switch
{
2 => Method2(maxPriority, isDone),
_ => Method1(maxPriority, isDone),
}
private async Task<IViewComponentResult> Method1(
int maxPriority, bool isDone)
{
...
}
private async Task<IViewComponentResult> Method2(
int maxPriority, bool isDone)
{
...
}
@await Component.InvokeAsync("PriorityList", new { method = 1, maxPriority = 4, isDone = true })
@await Component.InvokeAsync("PriorityList", new { method = 2, maxPriority = 4, isDone = true })
