提取c#代码文件中的方法块

　　   此方法是取C#文件里面的方法块，并删除缩进符，感觉写得还是比较容易懂的，所以收藏下，以便将来用到.

      　private static string GetCodeBlock(string allCode, string blockName)
        {
            int blockStart = allCode.IndexOf(blockName, StringComparison.OrdinalIgnoreCase);

            if (blockStart == -)
                return "// " + blockName + " code not found";
            blockStart = allCode.LastIndexOf(Environment.NewLine, blockStart, StringComparison.OrdinalIgnoreCase);
            if (blockStart == -)
                blockStart = ;
            else
                blockStart += Environment.NewLine.Length;

            int pos = blockStart;
            int braceCount = ;
            char c;
            do
            {
                pos++;

                c = allCode[pos];
                switch (c)
                {
                    case '{':
                        braceCount++;
                        break;

                }
            } while (pos < allCode.Length && !(c == '}' && braceCount == ));

            int blockEnd = pos;

            string blockCode = allCode.Substring(blockStart, blockEnd - blockStart + );

            return removeIndent(blockCode);
        }

            }

            StringBuilder builder = new StringBuilder();
            string[] codeLines = code.Split(new string[] { Environment.NewLine }, StringSplitOptions.None);
            foreach (string line in codeLines)
            {
                if (indentSpaces < line.Length)
                    builder.AppendLine(line.Substring(indentSpaces));
                else
