推荐答案

这是因为C＃区分大小写： .text与.Text不同。

尝试用大写的'T'替换以小写't'开头的所有.Text：

That's because C# is case sensitive: ".text" is not the same as .Text".
Try replacing all the ".Text" that starts with a lowercase 't' with uppercase 'T':

txtafricancoffee.Text = "0";
txtAmerican.Text = "0";
txtBlack.Text = "0";
txtboston.Text = "0";
txtcappuccino.Text = "0";
Txtcarlton.Text = "0";
txtcoffee.Text = "0";
txtespresso.Text = "0";
txticedcappuccino.Text = "0";
txticedlatte.Text = "0";
txtkilburn.Text = "0";
txtlagos.Text = "0";
txtlattle.Text = "0";
txtqueens.Text = "0";
Txtred.Text = "0";
txtvalue.Text = "0";
lblcostcakes.Text = "0";
lblcostdrink.Text = "0";
lblservice.Text = "1.75";

虽然你可能想检查你的控件n ames以及：有些是正确的camelCased： txtAmerican ， txtBlack ，而有些则不是： txtafricancoffee ， txtboston - 如果它们也不匹配，你也会收到错误。

Though you might want to check your control names as well: Some are correctly camelCased: txtAmerican, txtBlack, while some aren't: txtafricancoffee, txtboston - if they don't match either, you will get an error on them also.
