Converting A String To Different Cases And Humanizer

1. Converting Pascal Case to Camel Case: Using shortcut
   
   You can just select the first character of the string and use the shortcut “Ctrl+U” and it will convert the first character of the string to Lower case.
   
   The shortcut option is not limited to C#. Shortcut option can be used with any language opened inside Visual Studio because it is a feature of Visual Studio.
   
   Let’s do Some More Conversion
   
   Convert
   
   1. <p ng-bind="EmployeeDetails.FirstName"></p>
   2. <p ng-bind="EmployeeDetails.MiddleName"></p>
   3. <p ng-bind="EmployeeDetails.LastName"></p>
   4. <p ng-bind="EmployeeDetails.CurrentDesignation"></p>
   5. <p ng-bind="EmployeeDetails.Salary"></p>
   6. <p ng-bind="EmployeeDetails.Age"></p>
   7. <p ng-bind="EmployeeDetails.MobileNumber"></p>
   8. <p ng-bind="EmployeeDetails.EmailId"></p>
   9. <p ng-bind="EmployeeDetails.FacebookId"></p>
   10. <p ng-bind="EmployeeDetails.TwitterId"></p>
   To
   
   1. <p ng-bind="employeeDetails.firstName"></p>
   2. <p ng-bind="employeeDetails.middleName"></p>
   3. <p ng-bind="employeeDetails.lastName"></p>
   4. <p ng-bind="employeeDetails.currentDesignation"></p>
   5. <p ng-bind="employeeDetails.salary"></p>
   6. <p ng-bind="employeeDetails.age"></p>
   7. <p ng-bind="employeeDetails.mobileNumber"></p>
   8. <p ng-bind="employeeDetails.emailId"></p>
   9. <p ng-bind="employeeDetails.facebookId"></p>
   10. <p ng-bind="employeeDetails.twitterId"></p>
   As we know, most of the popular text editors like Visual Studio, Notepad++, Sublime etc. provides the feature of box selection (Vertical Selection). Hence, select the first character of the string “EmployeeDetails” vertically and the press Ctrl+U. Again, select first character of each attribute vertically and then press Ctrl+U.
   
   e.g.
   
   
   
   Press Ctrl+U and repeat same for the attributes of employee details.
   
   For box selection we use the shortcut key Ctrl+Shift+ Arrow
   
   1. Ctrl + Shift + Down Arrow => select vertically down.
   2. Ctrl + Shift + Up Arrow => select vertically up
   3. Ctrl + Shift + Right Arrow => select horizontally right
   4. Ctrl + Shift + Left Arrow => select horizontally left
   
   Or you can use Ctrl + Shift and drag mouse to select a rectangular area.
   
   We can also change multiple line vertically e.g. change EmployeeDetails to empDtls
   
   
   Vertical selection provides a lot more features but I am not going to explain all those features here.
   
   
2. Converting Pascal Case to Camel Case: Using String class methods
   
   1. string txt = "WelcomeToCaseConversionLearning";
   2. var txt2 = txt.Insert(0, txt[0].ToString().ToLower()).Remove(1, 1);
   In the same way, you can use methods for conversion to other case types.
   
   Have a look at the code snippet shown below which will provide you with the complete idea about the method available for case conversion in TextInfo & String class.
   
   1. #region String Class Methods
   2. //Case Conversion Example using String Class Methods
   3. string txt = "WelcomeToCaseConversionLearning";
   5. //Converting a string to upper case.
   6. WriteLine(txt.ToUpper());
   8. //Converting a string to lower case.
   9. WriteLine(txt.ToLower());
   10. #endregion
   12. #region TextInfo Class Methods
   13. //Case Conversion Example using TextInfo Class Methods
   14. string txt2 = "welcomeTocaseconversionLEarning";
   15. TextInfo textinfo = new CultureInfo("en-US", false).TextInfo;
   17. //Converting a string to upper case.
   18. WriteLine(textinfo.ToUpper(txt2));
   20. //Converting a string to lower case.
   21. WriteLine(textinfo.ToLower(txt2));
   23. //Converting a string to Title case
   24. WriteLine(textinfo.ToTitleCase("welcome To CASe conversion LEArning"));
   25. #endregion

Until now, you may have been thinking that if we can achieve something easily using String class or TextInfo class methods then why I am using Humanizer? Let me show you some examples after which you will understand why we need Humanizer.

1. Convert a string to pascal case
   
   1. WriteLine("welcomeTo_CaseConversion_Learning".Pascalize());
   2. //output: WelcomeToCaseConversionLearning
2. Convert a string to camel case
   
   1. WriteLine("WelcomeTo_Case_Conversion_Learning".Camelize());
   2. //output :welcomeToCaseConversionLearning
3. Convert a string to lower case.
   
   1. WriteLine(txt3.Humanize(LetterCasing.LowerCase));
   2. //output: welcome to case conversion learning
4. Convert a string to upper case.
   
   1. WriteLine(txt3.Humanize(LetterCasing.AllCaps));
   2. //Output: WELCOME TO CASE CONVERSION LEARNING
5. Convert a string to sentence case.
   
   1. WriteLine(txt3.Humanize(LetterCasing.Sentence));
   2. //output: Welcome to case conversion learning
6. Convert a string to Title Case
   
   1. WriteLine(txt3.Humanize(LetterCasing.Title));
   2. //Output: Welcome To Case Conversion Learning
7. Pluralize a string
   
   1. WriteLine("Employee".Pluralize());
   2. //Output: Employees
8. Singularize a string
   
   1. WriteLine("Employees".Singularize());
   2. //Output: Employee
9. Add Underscore
   
   1. WriteLine("Welcome to case conversion learning".Underscore());
   2. //Output: welcome_to_case_conversion_learning
10. Convert underscore to dash or hyphen
    
    1. WriteLine("welcome_to_case_conversion_learning".Hyphenate());
    2. WriteLine("welcome_to_case_conversion_learning".Dasherize());
    3. //Output : welcome-to-case-conversion-learning
    4. //Output : welcome-to-case-conversion-learning

Apart from these examples, you can do hundreds of other types of conversion and formatting using Humanizer. For more details, visit here
