推荐答案

if (textBox1.Text.EndsWith('',''))
   textBox1.Text = textBox1.Text.SubString(0, textBox1.Text.Length -1);

您可以尝试:
textbox.text.TrimEnd({''，''})

缺点(或优点)是，所有逗号最后都被删除，而不仅仅是一个.

否则，只需检查字符串中的最后一个字符，如果它是逗号，则将其删除.

祝你好运！

You could try:
textbox.text.TrimEnd({'',''})

A disadvantage (or advantage) is that all comma''s are removed at the end and not just one.

Otherwise just check the last character in the string and remove this if it is a comma.

Good luck!

string str = textbox1.text;
int i = str.length;
如果(str(i-1).tostring()==，")
str = str.remove(str.length-1);


尝试获取代码的逻辑插入.

string str = textbox1.text;
int i = str.length;
if (str(i-1).tostring() == ",")
str = str.remove(str.length-1);


try to get logic insted of code.
