{

char[] Arrchar = new char[10]{'. ', ', ', ', ', '! ','、','？ ', ' * ', ' ... ', ' ￥ ', ' $ '};

StringBuilder sb = new StringBuilder ();

int i = 0;

foreach (char char in str)

{

BOOL Biscontain = false;

for (int j = 0; J < Arrchar.length; J + +)

{

if (Char.compareto (arrchar[j]) = = 0)

{

Biscontain = true;

Break

}

}

if ((int) Char <= 127 | | biscontain)

i + 1;

Else

i = 0;

Sb. Append (Convert.ToString (Char));

if (i > Len)

{

Sb. Append (tag);

i = 0;

}

}

Return SB. ToString ();

}
