试试这个：

  string  s =   ABDCEFG * HI跨度>; 
s = s.Replace（  * HI，  HI）; 

当然你也可以使用Remove，看看：http://msdn.microsoft.com/de-de/library/d8d7z2kk%28v=vs.110%29.aspx [ ^ ]

  public   string 删除（
 int  startIndex，
 int  count 
）

在你的情况下它会是这样的（未经测试）：

  string  s =   ABDCEFG * HI; 
 int  nIndex = s.LastIndexOf（'  *'跨度>）; 
 if （nIndex >   0 ）
s = s.Remove（nIndex，nIndex + 1）; 

  string  RemoveCharacter（字符串源， char  c）
 {
 return  source.Replace（c.ToString（）， ）; 
} 

例如删除ABCDEFGH * IJK * LMN *中的所有字符'*' PQRST * UVWXYZ **

  string  s =   ABCDEFGH * IJK * LMN * PQRST * UVWXYZ **; 
s = RemoveCharacter（s，'  *'）; 

I have tried a lot of ways to get rid off a part of a string, for example lets take string s = "ABCDEFG*HI" and I wanted to remove the * symbol ONLY.

I have seen a lot of examples in *** in doing such thing but the solution they provided only supports removing the selected index of a CHAR and forward...

string s = "ABDCEFG*HI";
s = s.Remove( s.LastIndexOf('*') );
//The output was supposed to be ABCDEFGHI without the * symbol, but in reality, it turns out to be ABCDEFG

I also tried using s.IndexOf instead of s.LastIndexOf, but still no difference...
Any help would be much appreciated, thank you

Try this:

string s = "ABDCEFG*HI";
s = s.Replace("*HI", "HI");

Surely you can use Remove as well, take a look: http://msdn.microsoft.com/de-de/library/d8d7z2kk%28v=vs.110%29.aspx[^]

public string Remove(
    int startIndex,
    int count
)

In your case it would be something like this (not tested):

string s = "ABDCEFG*HI";
int nIndex = s.LastIndexOf('*');
if (nIndex > 0)
   s = s.Remove( nIndex, nIndex+1 );

string RemoveCharacter(string source, char c)
  {
      return source.Replace(c.ToString(),"");
  }

For example to remove all the character '*' in "ABCDEFGH*IJK*LMN*PQRST*UVWXYZ**"

string s="ABCDEFGH*IJK*LMN*PQRST*UVWXYZ**";
s=RemoveCharacter(s,'*');
