Apr 23, 2014 · If by size you mean how many characters, then Length is the property you are looking for "".Length // 0 "1".Length // 1 "12".Length // 2 If by size you mean how many bytes then this is dependant on encoding and you can use the answer Snake Eyes has given

Feb 23, 2019 · a.Length will give the number of elements of a. If b is a rectangular multi-dimensional array (for example, int[,] b = new int[3, 5];) b.Rank will give the number of dimensions (2) and. b.GetLength(dimensionIndex) will get the length of any given dimension (0-based indexing for the dimensions - so b.GetLength(0) is 3 and b.GetLength(1) is 5).

Apr 8, 2011 · I have a collection of string in C#. My Code looks like this: string[] lines = System.IO.File.ReadAllLines(@"d:\SampleFile.txt"); What i want to do is to find the max length of string in that collection and store it in variable. Currently, i code this manually, like?

Aug 11, 2018 · 2) When you're trying to get the rest of the string all the way to the end, use the other signature without the length: public string Substring(int startIndex) This is much easier to read and write than having to calculate the length of the string which you're doing wrong anyway, because promotionBody.Length - 1 will be beyond the length of the ...

Jan 3, 2012 · Are you asking how much memory a string object occupies, or how many bytes the representation of a string will occupy when written to a file or sent over a network (i.e. encoded), because those are two completely different questions. majidgeek almost answered the former while diya answered the latter (at least for two common encodings).

Jul 10, 2013 · I want to write an extension method to get the value of the MaximumLength property on the StringLength attribute. For example, I have a class: public class Person { [StringLength(MaximumLength=1000)] public string Name { get; set; } } I want to be able to do this: Person person = new Person(); int maxLength = person.Name.GetMaxLength();

Jul 17, 2017 · I have 2D array of string defined as string[][] input_data; I can count the number of rows by input_data.GetLength(0) but if I use input_data.GetLength(1) to get number of column, I always get

Nov 11, 2014 · Assuming your problem was length instead of Length, you can filter out only the values you need using a Where clause: string[] myArray = { "stringone", "stringtwo", "stringthree" }; foreach (string thing in myArray.Where(thing => thing.Length < 10)) { // Here you'll only iterate values // whos length is less than 10 }

Jun 21, 2019 · strings.Aggregate(string.Empty, (seed, f) => f?.Length ?? 0 > seed.Length ? f : seed); Aggregate syntax is slightly harder to read than the other methods, but strictly speaking it's more efficient than the other approaches I see here as it …

So basically the method uses a fakeimage with dimensions (1,1) to compute the length of the string, in this case the width of the image created from your chosen text. An example of how to use it ends up like this: string myTxt = "Hi there"; double …
