C# 如何在Xamarin IOS中将参数传递给事件处理程序

如何将字符串参数传递给EventHandler

视图控制器（A） 书面事件处理程序

    public event EventHandler ValueChanged; 

    void ResponseCompleted(object sender, CommonCode.ResponseEventArgs e){
        this.InvokeOnMainThread (delegate { 

        if (ValueChanged != null) {
        ValueChanged (this, new EventArgs (e.ResponseData));
// e.ResponseData is an String datatype.
         }
     });
    }

视图控制器（B）

您可以使用通用EventHandler。例如：

public event EventHandler<string> ValueChanged;

void ResponseCompleted(object sender, CommonCode.ResponseEventArgs e){
    this.InvokeOnMainThread (delegate { 

    var handler = ValueChanged;
    if (handler != null)
        handler(this, e.ResponseData);
    });
}

relatedDataSource.ValueChanged += (s, responseData) => {
    //Your data is in responseData variable
}

公共事件事件处理程序值已更改；
void ResponseCompleted（对象发送方，CommonCode.ResponseEventArgs e）{
this.InvokeOnMainThread（委托{
var handler=ValueChanged；
if（处理程序！=null）
处理程序（此，即响应数据）；
});
}
relatedDataSource.ValueChanged+=（s，responseData）=>{
//您的数据在responseData变量中
}

public event EventHandler<string> ValueChanged;

void ResponseCompleted(object sender, CommonCode.ResponseEventArgs e){
    this.InvokeOnMainThread (delegate { 

    var handler = ValueChanged;
    if (handler != null)
        handler(this, e.ResponseData);
    });
}

relatedDataSource.ValueChanged += (s, responseData) => {
    //Your data is in responseData variable
}
