C# - 将随机数生成到字段中

Question

我希望能够生成一个随机数，例如WXYZ，将输入到文本框字段中，目前我有这个:

textBox5.Text = "<RandomNumberHere>".ToString();

Answer 1

您只需要 Random 类。

分解声明:

//upperLimitPlusOne is an int which is 1 + whatever you want your max number to be
Random rnd = new Random();
int randomNumber = rnd.Next(0, upperLimitPlusOne);
textbox5.Text = randomNumber.ToString();

更简洁:

//same upperLimitPlusOne
Random rnd = new Random();
Textbox5.Text = (rnd.Next(0, upperLimitPlusOne)).ToString();
