strPrint = ""
strPAD = Space(12)
LSet strPAD = Mid(Trim(rsVoucher.Fields("Reference")) & "", 1, 12)

strPAD = temp_reference + (new string(' ', 12 - temp_reference.Length));
strPrint = strPAD + " "; //13

Answer 1

您正在寻找：＆＃39; PadLeft＆＃39;字符串对象的方法。

你的代码看起来像......

string temp_reference = reference.PadLeft(12, ' ');

if (temp_reference.Length > 12)
{
     temp_reference = temp_reference.Substring(0, 12) + "";
}

temp_reference += " ";
