error CS0103: The name ‘print‘ does not exist in the current context（Print/Debug.log）异常

print 在unity报错，疑难杂症

代码：`using System.Collections;
using System.Collections.Generic;
using System.Diagnostics;
using UnityEngine;
using Debug = UnityEngine.Debug;

///
///
///
public class Test : MonoBehaviour
{
void Start()
{
TestSingleton.Instance.myfunc();
}
}

public class TestSingleton : Singleton
{
public void myfunc()
{
//Debug.log(“TestSingleton”);
print(“TestSingleton”);
}
}`

解决办法

有谁知道为什么在第二个Class类里面写Print会报错？
