C#中的枚举问题 [英] problem of enum in c#

问题描述

你好朋友
我有一个枚举

Hello friends
i have a enum

private enum enumIC
        {
            eSelect,
            eID,
            eEdit,
            eCETSH,
            eDesc,
            eTGoods,
            eSchedule,
            eUOM,
            eRODA,
            eRODS,
            eDel
        }

iam在验证中使用枚举数组

iam using array of enum in validation

object[] obj = new object[] { (int)enumIC.eCETSH , (int)enumIC.eDesc, (int)enumIC.eTGoods, (int)enumIC.eUOM, (int)enumIC.eRODA, (int)enumIC.eRODS};
string st = GetobjArrayToString(obj);

private string GetobjArrayToString(object[] obj)
        {
            string str = "";
            for (int i = 0; i < obj.Length; i++)
            {
                str = Convert.ToString(obj[i]) + ",";
            }
            return str;
        }

我必须使用此方法将enum(value)的数组更改为string和iam，是否有任何更好的方法做到这一点

[edit]已添加代码块-OriginalGriff [/edit]

i have to change this array of enum(value) to string and iam using this method is there any better way of doing this

推荐答案

这可能对您想做的事情有些矫kill过正，但是...
枚举元素的人类可读字符串 [

This may be a bit overkill for what you want to do, but...
Human readable strings for enum elements[^]

BTW: Why are you declaring it as an object array? Why not as an array of enumIC instead?


because this is my function

public static void ValidateGridFields(string ColumnList, int iRow, DataGridView Grid)
        {
            string[] sColumn = ColumnList.Split(',');
            for (int i = 0; i < sColumn.Length; i++)
            { 
                int CNo = Convert.ToInt32(sColumn[i]);
                if (Grid[CNo, iRow].Value + "" == "")
                    Grid.Rows[iRow].Cells[CNo].Style.BackColor = Color.LightBlue;
                else
                {
                    if (Grid.Rows[iRow].Cells[CNo].Style.BackColor == Color.LightBlue)
                        Grid.Rows[iRow].Cells[CNo].Style.BackColor = Color.White;
                }
            }
        }

用于评估网格
我想发送这样的参数

for valadating grid
and i want to send argument like this

ValidateGridFields("1,2,3,4",1,DataGridView1

第一个参数是我们的价值



啊!那么，您想要的是一个枚举值数组，并返回一串数字值?
我将使用枚举值的数组:

first argument is our value



Ah! So what you want is to be handed an array of enumIC values, and return a string of the numerical values?
I would use an array of the enum values:

private enum enumIC
    {
    eSelect,
    eID,
    eEdit,
    eCETSH,
    eDesc,
    eTGoods,
    eSchedule,
    eUOM,
    eRODA,
    eRODS,
    eDel
    }
enumIC[] obj = new enumIC[] { enumIC.eCETSH, enumIC.eDesc, enumIC.eTGoods, enumIC.eUOM, enumIC.eRODA, enumIC.eRODS };

    ...
    Console.WriteLine(GetStringFromEnumArray(obj));
    ...

private static string GetStringFromEnumArray(enumIC[] ar)
    {
    StringBuilder sb = new StringBuilder();
    string sep = "";
    foreach(enumIC e in ar)
        {
        sb.AppendFormat("{0}{1}", sep, (int)e);
        sep = ",";
        }
    return sb.ToString();
    }

有更好的方法.
尝试Enum.GetNames()方法.

示例

There is a better way.
Try the Enum.GetNames() method.

Example

foreach(string s in Enum.GetNames(typeof(enumIC)))
            Console.WriteLine(s);
