无返回异步操作
ActionAsync
public class ActionAsync : Operator
{
private readonly Action _action;
protected ActionAsync()
{
}
public ActionAsync(Action action)
: this()
{
this._action = action;
}
public override IAsyncResult Invoke()
{
var middle = _action.BeginInvoke(CompletedCallBack, null);
SetAsyncResult(middle);
return middle;
}
public override void CompletedCallBack(IAsyncResult ar)
{
try
{
_action.EndInvoke(ar);
}
catch (Exception exception)
{
this.CatchException(exception);
}
ContinueAsync();
}
}
public class ActionAsync<T> : ActionAsync
{
public T Result;
private readonly Action<T> _action1;
protected readonly T Parameter1;
public ActionAsync()
{
}
public ActionAsync(T parameter)
{
this.Parameter1 = parameter;
}
public ActionAsync(Action<T> action, T parameter)
{
this._action1 = action;
this.Parameter1 = parameter;
}
public override IAsyncResult Invoke()
{
var result = _action1.BeginInvoke(Parameter1, CompletedCallBack, null);
SetAsyncResult(result);
return result;
}
public override void CompletedCallBack(IAsyncResult ar)
{
try
{
_action1.EndInvoke(ar);
}
catch (Exception exception)
{
this.CatchException(exception);
}
ContinueAsync();
}
}
有返回异步
FuncAsync实现了IFuncOperationAsync接口
IFuncOperationAsync
public interface IFuncOperationAsync<T>
{
void SetResult(T result);
T GetResult();
}
- SetResult(T result):异步操作完成设置返回值
-
GetResult():获取返回值
1）、FuncAsync
public class FuncAsync<TResult> : Operator, IFuncOperationAsync<TResult> { private TResult _result; public TResult Result { get { if (!Middle.IsCompleted || _result == null) { _result = GetResult(); } return _result; } } private readonly Func<TResult> _func1; public FuncAsync() { } public FuncAsync(Func<TResult> func) { this._func1 = func; } public override IAsyncResult Invoke() { var result = _func1.BeginInvoke(CompletedCallBack, null); SetAsyncResult(result); return result; } public override void CompletedCallBack(IAsyncResult ar) { try { var result = _func1.EndInvoke(ar); SetResult(result); } catch (Exception exception) { this.CatchException(exception); SetResult(default(TResult)); } ContinueAsync(); } public virtual TResult GetResult() { Wait(); return this._result; } public void SetResult(TResult result) { _result = result; } } public class FuncAsync<T1, TResult> : FuncAsync<TResult> { protected readonly T1 Parameter1; private readonly Func<T1, TResult> _func2; public FuncAsync(Func<T1, TResult> action, T1 parameter1) : this(parameter1) { this._func2 = action; } protected FuncAsync(T1 parameter1) : base() { this.Parameter1 = parameter1; } public override IAsyncResult Invoke() { var result = _func2.BeginInvoke(Parameter1, CompletedCallBack, null); SetAsyncResult(result); return result; } public override void CompletedCallBack(IAsyncResult ar) { try { var result = _func2.EndInvoke(ar); SetResult(result); } catch (Exception exception) { CatchException(exception); SetResult(default(TResult)); } ContinueAsync(); } }
