我的表单上有一个 listView.我想在程序运行期间添加一些东西.
I have a listView on my form. I want to add stuff to it durring the program is running.
这是我使用的代码
public void FillList(string[] Name,int[] empty,int[] Population,int[] Max,int[] Check,int size)
{
if (this.InvokeRequired)
{
this.Invoke((MethodInvoker)delegate
{
for (int i = 0; i < size; i++)
{
ListViewItem item = new ListViewItem(Name[i]);
item.SubItems.Add(empty[i].ToString); //error
item.SubItems.Add(Population[i].ToString); //error
item.SubItems.Add(Max[i].ToString); //error
if (Check != 1)
item.SubItems.Add("No");
else
item.SubItems.Add("Yes");
listView1.Items.Add(item);
}
});
}
}
参数必须是字符串,我尝试了 .ToString
,但我明白了:
the parameter must be string and I tried .ToString
, but I get this:
参数1":无法从方法组"转换为字符串"
Argument '1': cannot convert from 'method group' to 'string'
你缺少方法调用的括号:
You are missing the parentheses of the method call:
ToString()
没有括号,表达式是一个方法组——即对一个或多个重载方法的引用.
Without the parentheses, the expression is a method group— that is, a reference to one or more overloaded methods.
这篇关于Int 到字符串:无法从“方法组"转换为“字符串"的文章就介绍到这了,希望我们推荐的答案对大家有所帮助,也希望大家多多支持跟版网!
