(E.g. convert é to e , so would become creme brulee ) What is the best method for achieving this? 回答1: I've not used this method, but Michael Kaplan describes a method for doing so in his blog post (with a confusing title) that talks about stripping diacritics: Stripping is an interesting job (aka On the meaning of meaningless, aka All Mn characters are non-spacing, but

The easy way would be to put all the chars in a stack and put them back into a string again but I doubt that's a very efficient way to do it. And please do not tell me to use some built in function in Java. I am interested in learning how to do it not to use an efficient function but not knowing why it's efficient or how it's built up. 回答1: You say you want to know the most efficient way and you don't want to know some standard built-in way of

StringBuilder sample = new StringBuilder (); StringBuilder referToSample = sample ; sample . append ( "A" ); referToSample . append ( "B" ); System . out . println ( referToSample ); This will print AB that also proves the same.

It all exists within the first cell of each row. StringBuilder sb = new StringBuilder(); foreach (DataColumn col in dt.Columns) { sb.Append(col.ColumnName + ','); } sb.Remove(sb.Length - 1, 1); sb.Append(Environment.NewLine); foreach (DataRow row in dt.Rows) { for (int i = 0; i Thanks. 回答1: The following shorter version opens fine in Excel, maybe your issue was the trailing comma .net = 3.5

Is there anything out there that might let me do something more along the lines of this though? DesiredStringThinger text = new DesiredStringThinger (); text . append ( "line1" ); text . append ( "line2" ); text . append ( "line3" ); useString ( text . toString () ); Obviously, it does not need to work exactly like that, but I think I get the basic point across.

What's the difference between xlsSheet.Write("C" + rowIndex.ToString(), null, title); and xlsSheet.Write(string.Format("C{0}", rowIndex), null, title); Is one "better" than the other? And why? 回答1: Before C# 6 To be honest, I think the first version is simpler - although I'd simplify it to: xlsSheet.Write("C" + rowIndex, null, title); I suspect other answers may talk about the performance hit, but to be honest it'll be

My goal is to iterate through these, and get the installation path of a few of them. PSEUDOCODE ( combining multiple languages :) ) foreach InstalledSoftwareProduct if InstalledSoftwareProduct.DisplayName LIKE *Visual Studio* print InstalledSoftwareProduct.Path 回答1: You can use MSI api functions to enumerate all installed products. Below you will find sample code which does that. In my code I first enumerate all products, get the product name and if it contains the
