[解决办法]
int i = 0;
i.ToString( "000 ");
[解决办法]
public string Convert(int i, lenght length)
{
string ret = i.ToString();
for (j = 0; j < length - ret.Length; j++ )
{
ret += "0 ";
}

return ret;
}

顶楼上
[解决办法]
Text = i.ToString( "D3 ");
[解决办法]
int i = 123;
string s = i.ToString( "000 ");

[解决办法]
ret += "0 ";
Sorry
应该是
ret = "0 " + ret;
[解决办法]
int n = 10;
Console.WriteLine( " n is :{0:d3} ",n);
[解决办法]
i.ToString().PadLeft(3, '0 ');
[解决办法]
str.PadLeft(3, '0 ');
[解决办法]
PadLeft(3, '0 ');
