继续<label>在C＃中像java一样</label>

Question

I need C# equivalent to Java's continue ?

i have

for (String b : bar) {
    <label>
    try {
    }
    catch (EndpointNotFoundException ex) {
    continue <label>
    }
  }

how can i simulate this in C#. i need that when i get exception that i repeat code not go on.

Answer 1

If you only need to continue to the next loop iteration, use continue .

c# also has labels (which you can jump to with goto ), but please don't use them.

Answer 2

使用goto <label>;

Answer 3

Why not simply add a control variable?

foreach (String b in bar) {
  bool retry;
  do {
    retry = false;
    try {
      // ...
    }
    catch (EndpointNotFoundException ex) {
      retry = true;
    }
  } while (retry);
}

or

var strings = bar.GetEnumerator<string>();
var retry = false;
while (retry || strings.Next()) {
  var b = strings.Current;
  retry = false;
  try {
    // ...
  }
  catch (EndpointNotFoundException ex) {
    retry = true;
  }
}

I don't think what you're trying to do is wise at all - do you have any reason to expect that you won't hit a scenario where you always get an exception on a particular iteration?

Anyhow, to do what you want to do without goto , look at this:

foreach (String b in bar) { 
    while(!DidSomethingWithThisString(b))
        ;
  } 

bool DidSomethingWithThisString(string b)
{
    try { 
    } 
    catch (EndpointNotFoundException ex) { 
        return false;
    } 
    return true;
}
