Answer 1

       string str = @"http://202.205.170.240/neie/Lists/keywords/PersonalViews.aspx?PageView=Personal&ShowWebPart={61E679E8-5970-4E8E-9B9F-200B4778644E}";        int i=str.LastIndexOf('{');
        string str1 = str.Substring(i + 1);
        string str2 = str1.Substring(0, str1.Length - 1);

Answer 2

string s="fafdsafdas{61E679E8-5970-4E8E-9B9F-200B4778644E}fsafdsafa ";//首尾加了些乱七八糟的数据,测试INDEXOF及LASTINDEXOF.
int i=s.IndexOf('{');
int j=s.LastIndexOf('}');
s=s.SubString(i,j-i+1);
