C# 用变量的值通过反射获取变量的属性名

 

public class Test
{
    public const string test1 = "Test1";
    public const string test2 = "Test2";
}

 

private Test testObj = new Test();
private Type testType = testObj.GetType();
private PropertyInfo[] properties = testObj.GetProperties(BindingFlags.Instance | BindingFlags.Public | BindingFlags.NonPublic | BindingFlags.Static);

//传入Test类中的属性值"Test1"、"Test2"，输出属性名
public void GetTypeValue(string s)
{
    for (int i = 0; i < testType.GetFields().Length; i++)
    {
        if (testType.GetFields()[i] != null)
        {
            if (testType.GetFields()[i].GetValue(testObj) != null && testType.GetFields()[i].GetValue(testObj).ToString() == s)
            {
                Debug.LogError(testType.GetFields()[i].Name);
                break;
            }
        }
    }
}

或者下面这种方式也可以

private Type testType;
private FieldInfo[] fieldInfos;

public void GetTypeValue(ushort s)
{
    testType = typeof(Test);
    fieldInfos = testType.GetFields();
    
    for(int i = 0; i < fieldInfos.Length; i++)
    {
        if(fieldInfos[i] != null && fieldInfos[i].GetRawConstantValue() != null)
        {
            if (Convert.ToInt32(fieldInfos[i].GetRawConstantValue()) == s)
            {
                Debug.LogError(fieldInfos[i].Name);
            }
        }
    }
}
