推荐答案

对于问题中指定的要求，我认为可以声明AdmnNo 的公共变量，并且每次单击时其值都会增加按钮，如下所示，并且AdmId 是使用string.Format
生成的

For the requirement specified in the question, I think a public variable for AdmnNo can be declared and its value is incremented in each click of the button as shown below, and the AdmId is generated using string.Format

int AdmnNo = 0;
//Within the click event of the button
string AdmnId = string.Format("Adm{0:0000}",++AdmnNo);
Console.WriteLine (AdmnId);
