检查String是否为excel格式c＃

Question

我的程序允许我粘贴一个被复制并添加到列表视图的Excel。我想知道如何检查字符串是否真的是excel文件的副本。我找到了这个解决方案（c# : Excel : Determine if a string is a valid datasheet Range?），但它没有用。

from pyparsing import *

def pushFirst( strg, loc, toks ):
    toks[0][2], toks[0][1] = toks[0][1], toks[0][2]

def parseTerm(term):
    """
    EBNF syntax elements
    EXCLAM =  !
    HAT =  ^ 
    STAR =  *
    SEMI =  ; 
    LPAR =  (
    RPAR =  )
    """

    EXCLAM,HAT,STAR = map(Literal,"!^*")
    LPAR,RPAR = map(Suppress,"()")
    SEMI = Suppress(";")

    token = oneOf(list(alphas.upper()))
    expr = Forward()
    expr <<=    (
                    EXCLAM | 
                    Group(Word(alphas.upper()) + SEMI + ungroup(expr)) | 
                    Group(LPAR + expr + HAT + expr + RPAR).setParseAction( pushFirst ) | 
                    Group(LPAR + expr + STAR + expr + RPAR).setParseAction( pushFirst )
                )
    try:
        result = expr.parseString(term)   
    except ParseException as pe:
        print ' '*pe.loc + '^'
        print pe
    return result[0]



def computeTerm(term):
    print term


term = (parseTerm("(((AXX;!^B;!)^C;D;!)*E;!)"))

computeTerm(term)

上面链接中的解决方案表明了这个功能：

 String cp = Clipboard.GetText();
 string[] stringSeparators = new string[] { "\r\n" };
 string[] rows = cp.Split(stringSeparators, StringSplitOptions.None);
 for (int i = 0; i < rows.Length - 1; i++){
    ListViewItem tempT = new ListViewItem(rows[i].Split('\t'));
    listView.Items.Add(tempT);
 }

错误说：

private bool IsRange(string refr) {
   try {
      Range(refr);
      return true;   // if no error occurred, refr is a valid range
   }
   catch {
      return false;   // not a valid range
   }
}
