当我在我的项目中复制此代码时，我得到变量“store” [英] when i was copying this code in my project then i dint get the variable "store"

问题描述

private void dataGridView1_CellValueNeeded(object sender,
    DataGridViewCellValueEventArgs e)
{
    if (store.ContainsKey(e.RowIndex))
    {
        // Use the store if the e value has been modified
        // and stored.
        e.Value = store[e.RowIndex];
    }

推荐答案

商店不是一个功能它是一个数组/索引器到数据源。



右键单击Visual Studio中的单词，然后选择转到定义以查看类型。

store is not a function it is an array/indexer to a data source.

Right click on the word in Visual Studio and select "Go To Definition" to see what the type is.

如果你复制并粘贴了那个方法，你错过了名为store的成员。看起来它被声明为字典< int，Int> 。

If you copy and pasted that method, you missed out the member called store. It looks like it was declared as a Dictionary<int, Int>.
