这个while语句要怎么写？

[roopeman]

using System;
using System.Data;
using System.Diagnostics;
using System.Text.RegularExpressions;
public class Logtest
{
public static void Main(String[] args)
{
string machine = ".";
string log = "system";
EventLog aLog = new EventLog();
aLog.Log = log;
aLog.MachineName = machine;
int Num = aLog.Entries.Count;
Console.WriteLine("total"+Num.ToString());
//输出source为print的Message
While(aLog.Entries.Source=="print")
{

foreach (EventLogEntry entry in aLog.Entries)
{
Console.WriteLine("\t项：{0}", entry.Message);
}
}
}

}

不明白

[fellowcheng]

加ToString()

[zahuifan]

不会

[sskset]

???

[roopeman]

加了ToString()还是不行,错误说要加个";" .

[roopeman]

不要沉下去,希望有人能帮我.

[yanshizhuan]

是不是要改成: While("print".Equal(aLog.Entries.Source)),在字符串比较的时候不能用“==”。

[jacky_zhang888]

while第一字母是小写吧。

晕，搂主想干什么？
把你要干什么讲清楚啊，你是不是要aLog.Entries.Source=="print"时循输出？

[roopeman]

对不起,没写明白,就是想循环输出source 为"print"的message !

改成如下,编译可通过,可是只有第一个Console.WriteLine 有输出,第二个Console.WriteLine没有!

using System;
using System.Data;
using System.Diagnostics;
using System.Text.RegularExpressions;
public class logtest
{
public static void Main(String[] args)
{
string machine = ".";
string log = "system";
EventLog aLog = new EventLog();
aLog.Log = log;
aLog.MachineName = machine;
int Num = aLog.Entries.Count;
Console.WriteLine("total"+Num.ToString());
while(aLog.Source.ToString().Equals("Print"))


{ foreach (EventLogEntry entry in aLog.Entries)
{
Console.WriteLine("\t项：{0}", entry.Message);
}
}

}
}
