从java转换为C＃ [英] Convert from java to C#

问题描述

嘿伙计我想要你的帮助，所以java有Enumeration类，更具体地说它有一个布尔方法是允许你检查Enumeration是否包含元素的类。

Hey guys I want your help, so java has the Enumeration class and more specifically it has a boolean method is the class that allows you to check if the Enumeration contains element.

public String extractSelectAllValue(Hashtable pDataTable) {
Enumeration lKeyEnumeration;
String lKeyValue;
String lDataValue;
lKeyValue = "";
lDataValue = "";
try {
	lKeyEnumeration = pDataTable.keys();
	while(lKeyEnumeration.hasMoreElements()) {
	lKeyValue = (String)lKeyEnumeration.nextElement();
	lDataValue =  lDataValue +(String)pDataTable.get(lKeyValue) + "::";
    }
	return lDataValue;
    } catch(Exception e) {
      System.out.println("Error Extracting all Values of the list");
      e.printStackTrace();
      return "";
    }
	}

你明白了，我想知道c＃是否有这样的东西。因为我已经检查了Enum类，但我找不到任何反映它的方法。



感谢您的帮助。

you get the idea, I wanted to know if c# has something like that. Because I have already checked the Enum class and I did not find any method that mirrors that.

Thanks for your help.

推荐答案

如果您正在使用 Hashtable s，则可以执行以下操作：

If your are using Hashtables the in c# you can do this :

Hashtable hashtable = new Hashtable();
foreach (var key in hashtable.Keys)
{
    object o = hashtable[key]; // value of the key
    // do your stuff here
}

C＃还包含Enumaration class.Please看看下面的代码。

C# also contains the Enumaration class.Please check out the below code.

using System;
using System.Collections;

public virtual string extractSelectAllValue(Hashtable pDataTable)
{
System.Collections.IEnumerator lKeyEnumeration;
string lKeyValue;
string lDataValue;
lKeyValue = "";
lDataValue = "";
try
{
    lKeyEnumeration = pDataTable.Keys.GetEnumerator();
    while (lKeyEnumeration.hasMoreElements())
    {
    lKeyValue = (string)lKeyEnumeration.nextElement();
    lDataValue = lDataValue + (string)pDataTable[lKeyValue] + "::";
    }
    return lDataValue;
}
catch(Exception ex)
{
throw ex;
}
