How can I limit the length of a string to 150 characters?

c# string format max length
c# string max length
c# set string to fixed length
c# trim string to length
c# string length
c# if string length is greater than
c max string length attribute
c# string property set max length

I tried the following:

var a = description.Substring(0, 150);

However this gives a problem if the length of description is less than 150 chars. So is there another way I can limit the length to 150 that won't give an error when string length is for example 20.

var a = description == null 
        ? string.Empty 
        : description.Substring(0, Math.Min(150, description.Length));

Limiting the number of characters in a string, and chopping off the , I have the code to do this already, but I need to limit Strings, doubles and ints to a fixed-width size that is hard-coded in the code. So, suppose I  int maxLength = Math.Min(LongTitle.Length, 20); string title = LongTitle.Substring(0, maxLength); This can be turned into extension method: public static class StringExtensions { /// <summary> /// Truncates string so that it is no longer than the specified number of characters.

var a = description.Substring(0, Math.Min(150, description.Length));

Just grab the substring of either 150 characters, or the whole string, whichever is shorter.

C# Truncate String, This method restricts the maximum length of strings. Truncate: If the source is longer than the max length, we call Substring to get the first N characters. I am not sure exactly what you are asking, but if you want to know the maximum length of a string, this question can help you. If you want to limit the number of characters entered, I would suggest that you use server-side validation and/or client-side validation.

The String Length Attribute works for C#:

[StringLength(150)]

}

Is there any limit for the number of characters that I can assign? Its Integer.MAX_VALUE or 2^31-1 or about 2 billion. You are more likely to have memory problems before getting to this size. e.g. You need 4 GB for the String and 4 GB to create it.

Get string truncated to max length, If you're using C# 6.0, I believe you can drop the null-check: public static string WithMaxLength(this string value, int maxLength) { return value?

One is to use string functions, like the LEFT (), RIGHT () and SUBSTRING () functions, to return only a subset of the text. This does the job but, as we’ll see, can be impractical. Another approach is to use the TEXTSIZE setting. Let’s look at an example.

  • I have tested it in a ViewModel in WPF and it doesn't work with a TextBox. The documentation mentions ASP.NET. Maybe it's used only in that kind of applications.
