c＃以编程方式设置值按钮。

Question

如果我有100个按钮，我想设置文本=“保存”，并且id是一个像saveButton_1这样的自动编号，saveButton_2是做什么最好的方法？按钮不是动态生成的，可以通过后面的代码访问。

目前我喜欢但似乎很长。

saveButton_1.value = saveButton_2.value ... till 100 = "Save"

扩展位@Adil的回答，如果您有按钮的容器内，你可以让他们使用HtmlButton型

IEnumerable< HtmlButton> btns = buttonContainer.Controls.OfType<HtmlButton>(); 

if(btns != null) 
{ 
    //get only the ones that have a special class to know which ones you need to update 
    var btnList = btns.Where(x => x.Attributes["class"] == "save-button"); 

    //update the text for all that passed the filter 
    foreach(HtmlButton ctrl in btnList) 
    { 
     ctrl.InnerText = "Save Me"; 
    } 
} 

的Html

<div id="buttonContainer" runat="server"> 
    <button id="save1" type="button" class="save-button" runat="server">save 1</button> 
    <button id="save2" type="button" class="save-button" runat="server">save 1</button> 
    <button id="save3" type="button" class="save-button" runat="server">save 1</button> 
    <button id="save4" type="button" class="save-button" runat="server">save 1</button> 
    <button id="save5" type="button" runat="server">not save</button> 
    <button id="save6" type="button" class="save-button" runat="server">save 1</button> 
    <button id="save7" type="button" class="save-button" runat="server">save 1</button> 
    <button id="save8" type="button" class="save-button" runat="server">save 1</button> 
    <button id="save9" type="button" class="save-button" runat="server">save 1</button> 
</div> 

如果你没有在同一个容器上的按钮，那么你将需要循环通过你有的控件，以得到正确的htmlbuttons

Answer 2

foreach (Button btn in this.Controls.OfType<Button>()) 
    { 
     btn.Text = "Save"; 
    }
