当我尝试调试此代码(在C#WinForms中)时,它显示错误

"使用未分配的局部变量"在'arrlist [i]'

    int ticket_length = strarray.Length;
    string[] arrlist;
    int i = 0;      
    foreach(var control in this.Controls)
    {
        if(control is Label)

            i++;
        }
   }       
   for(var j=0;j<=ticket_length;j++)
   {
       for (var k …
