解决方案:

int enumValue = 2; // The value for which you want to get string 
string enumName = Enum.GetName(typeof(EnumDisplayStatus), enumValue);

同样，使用GetName比显式转换Enum更好。

[性能基准代码]

Stopwatch sw = new Stopwatch (); sw.Start (); sw.Stop (); sw.Reset ();
double sum = 0;
int n = 1000;
Console.WriteLine ("\nGetName method way:");
for (int i = 0; i < n; i++) {
   sw.Start ();
   string t = Enum.GetName (typeof (Roles), roleValue);
   sw.Stop ();
   sum += sw.Elapsed.TotalMilliseconds;
   sw.Reset ();
}
Console.WriteLine ($"Average of {n} runs using Getname method casting way: {sum / n}");
Console.WriteLine ("\nExplicit casting way:");
for (int i = 0; i < n; i++) {
   sw.Start ();
   string t = ((Roles)roleValue).ToString ();
   sw.Stop ();
   sum += sw.Elapsed.TotalMilliseconds;
   sw.Reset ();
}
Console.WriteLine ($"Average of {n} runs using Explicit casting way: {sum / n}");

(样本结果)

GetName method way:
Average of 1000 runs using Getname method casting way: 0.000186899999999998
Explicit casting way:
Average of 1000 runs using Explicit casting way: 0.000627900000000002

只需要:

string stringName = EnumDisplayStatus.Visible.ToString("f");
// stringName == "Visible"

将int类型转换为枚举类型:

EnumDisplayStatus status = (EnumDisplayStatus) statusFromDatabase;
string statusString = status.ToString();

我使用了下面给出的这个代码

 CustomerType = ((EnumCustomerType)(cus.CustomerType)).ToString()

DB到c#

EnumDisplayStatus status = (EnumDisplayStatus)int.Parse(GetValueFromDb());

c#到DB

string dbStatus = ((int)status).ToString();

你可以试试这个

string stringValue=( (MyEnum)(MyEnum.CSV)).ToString();
