如何从案例类别值中获取类别类型

Question

我有以下代码段：

case class Test(i:Int)

val b = Test // b: Test.type
val a = Test(1) // a: Test

是否有一种方法可以将类型为a的值Test转换为Test.type？

Answer 1

将 foreach (Control x in this.Controls) { if (x is Button) { Button newbut = (Button)x; newbut.FlatStyle = FlatStyle.Flat; newbut.FlatAppearance.BorderColor = Color.FromArgb(0, 255, 255, 255); newbut.FlatAppearance.BorderSize = 0; newbut.TabStop = false; } } 添加到libraryDependencies += scalaOrganization.value % "scala-reflect" % scalaVersion.value，然后您可以尝试

build.sbt
