Check If String Is Null / Zero Length

string strCheck = '';
bool checkString = String.IsNullOrEmpty(strText);

Shunning Extension Method To Filter Order And Sort- Linq

string[] names = { "Tom", "Dick", "Harry", "Mary", "Jay" };

IEnumerable<string> query =
  Enumerable.Select (
    Enumerable.OrderBy (
      Enumerable.Where (
        names, n => n.Contains ("a")
      ), n => n.Length
    ), n => n.ToUpper()
  );
  

Comapre Two Strings

string strReverse ="";
string straoriginal = "Test";
if ((string.Compare(strOriginal, strReverse , false)) < 0)
    {
        MessageBox.Show("Less");
    }
    else if ((string.Compare(strOriginal, strReverse , false)) > 0)
    {
        MessageBox.Show("Greater");
    }
    else if ((string.Compare(strOriginal, strReverse , false)) == 0)
    {
        MessageBox.Show("Equal");
    }

Reverse A String

string strReverse ="";
string straoriginal = "Test";
string strReverse= Microsoft.VisualBasic.Strings.StrReverse(strOriginal);
    MessageBox.Show(strReverse); 

Progressive Query - LINQ

Progessive form 
IEnumerable<string> filtered   = names.Where      (n => n.Contains ("a"));
IEnumerable<string> sorted     = filtered.OrderBy (n => n.Length);
IEnumerable<string> finalQuery = sorted.Select    (n => n.ToUpper());

Output

Harry
Mary
Jay

Jay
Mary
Harry

JAY
MARY
HARRY
 
 
 

 
 

                

Splitting A String Using String Function

string string1= "Split function";
string [] SplitString = string1.Split(new Char [] {' '});
MessageBox.Show(Convert.ToString(SplitString [0]));
MessageBox.Show(Convert.ToString(SplitString [1])); 

Fluent Query - LINQ

                    Fluent query - LINQ

string[] names = { "Tom", "Dick", "Harry", "Mary", "Jay" };

IEnumerable<string> query = names
	.Where   (n => n.Contains ("a"))
	.OrderBy (n => n.Length)
	.Select  (n => n.ToUpper());

Simple Filter Query - LINQ

                    Simple Filter Query 

from n in new[] { "Tom", "Dick", "Harry" }
where n.Contains ("a")
select n

Ouput: Harry                

Replace String With In String

string string1 = "Replace string";
string finalstring= string1 .Replace("replace", "Replaced");
MessageBox.Show("Final Value : " + finalstring); 

Filter Using Extension Method - LINQ

                    Extension method
