这是我的情况:我可以从数据库中检索数据,但是当我运行程序并填写Quantity列(在第三行)时,错误显示:索引超出范围。有谁知道为什么会这样?(当我尝试填写数量列(在第三行)时,出现错误)<-如下图所示。
这是我的程序的图像:
这是错误所在位置的图像:

这是我的问题:“我很困惑,当我尝试为“textBoxAllTotalContainer.Text = textBoxTotalContainer[0][0].Text”分配一个值时,代码正在运行。但是,当我尝试“textBoxAllTotalContainer.Text = textBoxTotalContainer[ 0][one(1)]",屏幕卡在那里(我必须停止从 Visual Studio 调试)"
textBoxTotalContainer 包含 17 个文本框,因此,我使用 [0][0] 到 [0][16],而 textBoxAllTotalContainer 包含 1 个文本框,所以我只使用 textBoxAllTotalContainer.Text
注意:“关键字(一),它假设为“1”<--数字,我写(一),因为当我尝试更改[0] [(这里应该是“1”)]时,文本自动更改为链接图像”
问题:**“当我尝试代码时
else if (textBoxQuantityContainer[0][0].Text == "1")
{
textBoxTotalContainer[0][0].Text = textBoxSubTotalContainer[0][0].Text;
textBoxAllTotalContainer.Text = textBoxTotalContainer[0][0].Text;
}
alltotalcontainer的文本框已打开(Rp 上的总计,文本框位于单词之后)在上图中,小计的文本框已打开(Rp 上的小计),totalcontainer的文本框已打开(Rp 上的总计,文本框位于文字下方),数量容器的文本框位于(数量)。在上面的代码中,显示textboxtotalcontainer上的文本框 1 与subtotalcontainer上的文本框 1 相同,并且alltotalcontainer与totalcontainer相同。**
但是,下面的代码它不起作用,屏幕卡在那里(鼠标消失,我什么也做不了,除非我在 Visual Studio 上按 SHIFT + F5):
else if (textBoxQuantityContainer[0][1].Text == "1")
{
textBoxTotalContainer[0][1].Text = textBoxSubTotalContainer[0][1].Text;
textBoxAllTotalContainer.Text = textBoxTotalContainer[0][1].Text;
}
谢谢
