问题 My database includes only Truck however my below select statment returns the rows with 'Truck' MyWebControl.Myfunction().Select("TransportationMode = '" + TRUCK + "'"); How can I make this select statement case sensitive ? 回答1: Set DataTable.CaseSensitive to True . Assuming Myfunction() returns a DataTable: string TRUCK = "trUck"; var dt = MyWebControl.Myfunction(); dt.CaseSensitive = True; dt.Select("TransportationMode = '" + TRUCK + "'"); 回答2: If you're at least on .NET 3.5 you could use

问题 The word "merge" does not refer to a git merge, but just moving all the files to the same directory. We somehow came to have two directories with the same name but different cases in our git repository. Windows is case-insensetive in this respect so it works fine just checking out all the files from both directories into one directory on disk. Still would like to get rid of this "duality" Is there a way to fix this using Windows git clients? I've tried git mv, but it appears to be case

问题 I set up a MyISAM table to do FULLTEXT searching. I do not want searches to be case-sensitive. My searches are along the lines of: SELECT * FROM search WHERE MATCH (keywords) AGAINST ('+diversity +kitten' IN BOOLEAN MODE); Let's say the keywords field I'm looking for has the value "my Diversity kitten". I noticed the searches were case-sensitive. I double-checked my collation on the search table, it was set to utf8_bin . D'oh! I changed it to utf8_general_ci . But my query is still case

问题 In a recent VB.NET project I adopted the naming conventions I'm used to using in C#. Namely, often calling a variable the same name as the class it references, only with a different case, e.g. Foo foo = new Foo(); // C# Dim foo As New Foo() ' VB.NET I find this is often the clearest way to write code, especially for small methods. This coding style obviously works fine in C#, being case sensitive, and because of the syntax highlighting provided by Visual Studio, it is very easy to see that

问题 We develop in a mixed environment - some people work on Macs and some work on Linux. This has proven to be a bit of a challenge at times, as those people who work on Linux are used to having their filesystems be case sensitive, so there's no issue committing (accidentally or otherwise) multiple files differing just by case. (e.g. FileName.ext versus filename.ext ) However, when the people on Macs go to check out the repository, having a case-insensitive filesystem means that the two files -

问题 Are .NET string functions like IndexOf("blah") case sensitive? From what I remember they aren't, but for some reason I am seeing bugs in my app where the text in the query string is in camel case (like UserID) and I'm testing for IndexOf("userid") . 回答1: Yes, string functions are case sensitive by default. They typically have an overload that lets you indicate the kind of string comparison you want. This is also true for IndexOf. To get the index of your string, in a case-insensitive way, you

问题 I am having difficulty with case sensitivity. Can we turn it off? A1 <- c("a", "A", "a", "a", "A", "A", "a") B1 <- c(rep("a", length(A1))) A1 == B1 # [1] TRUE FALSE TRUE TRUE FALSE FALSE TRUE should be all TRUE 回答1: There's no way to turn off case sensitivity of == , but coercing both character vectors to uppercase and then testing for equality amounts to the same thing: toupper(A1) [1] "A" "A" "A" "A" "A" "A" "A" toupper(A1)==toupper(B1) # [1] TRUE TRUE TRUE TRUE TRUE TRUE TRUE 回答2: As Josh
