c# - 如何优化此代码以创建文档库

Question

这是共享点代码，但我知道 C# 开发人员会理解它。

我现在想不出优化它的方法。想法是根据事件的创建创建文档库，文档库的名称是某种格式的开始日期 + 事件标题。

问题是当用户在同一天用相同的标题制作许多事件时。我用 IF 只对一次重复进行了处理。但应该有另一种更好的方法来做到这一点。

想法是在文档库的末尾连接一个数字/1/2/3等

using (SPSite oSPSite = new SPSite(SiteUrl))
            {
                using (SPWeb oSPWeb = oSPSite.RootWeb)
                {
                    if (oSPWeb.Lists[DocumentLibraryName] == null)
                    {
                        Guid ID = oSPWeb.Lists.Add(DocumentLibraryName, DocumentLibraryName + System.DateTime.Now.ToString(), SPListTemplateType.DocumentLibrary);
                        SPList oSPList = oSPWeb.Lists[ID];
                        DocumentLibraryLink = oSPList.DefaultViewUrl;
                        oSPList.OnQuickLaunch = false;
                        oSPList.Update();
                    }
                    else
                    {
                        if (oSPWeb.Lists[DocumentLibraryName + "/1"] == null)
                        {
                            Guid ID = oSPWeb.Lists.Add(DocumentLibraryName + "/1", DocumentLibraryName + System.DateTime.Now.ToString(), SPListTemplateType.DocumentLibrary);
                            SPList oSPList = oSPWeb.Lists[ID];
                            DocumentLibraryName = DocumentLibraryName + "/1";
                            DocumentLibraryLink = oSPList.DefaultViewUrl;
                            oSPList.OnQuickLaunch = false;
                            oSPList.Update();
                        }
                    }
                }
            }
        }

在伪代码中:

string docLibNameBase ="myLibname";
string docLibNameTemp = docLibNameBase; //we start with the calculated title
int iCounter = 1;

//we check if the currently calculated title is OK
while (listExists(docLibNameTemp, yourWeb)) {
    docLibNameTemp = docLibNameBase + "/" + iCounter.toString();
}
//this is where you create the new list using docLibNameTemp as a good title


bool listExists(string docLibName, SPWeb web){
   try {
      //if there is no list with such name, it will throw an exception
      return (web.Lists[docLibname]!=null);
   } catch{
        return false;
   }
}
