How to select again the previously selected text after changing its case in WinForms SyntaxEditor (EditControl)?

Select the text

The SetSelection() method is used to select the text in EditControl. We need to invoke SetSelection() method after converting the case of the SelectedText.

//Selecting the text after converting to lowercase
string lowerCaseStr;
lowerCaseStr = this.editControl1.SelectedText.ToLower();
this.editControl1.SelectedText = lowerCaseStr;
this.editControl1.SetSelection(col - lowerCaseStr.Length, this.editControl1.CurrentLine, col, this.editControl1.CurrentLine);
//Selecting the text after converting to uppercase
string upperCaseStr;
upperCaseStr = this.editControl1.SelectedText.ToUpper();
this.editControl1.SelectedText = upperCaseStr;
this.editControl1.SetSelection(col-upperCaseStr.Length, this.editControl1.CurrentLine, col, this.editControl1.CurrentLine);

`Selecting the text after converting to lowercase
Dim lowerCaseStr As String
lowerCaseStr = Me.editControl1.SelectedText.ToLower()
Me.editControl1.SelectedText = lowerCaseStr
Me.editControl1.SetSelection(col - lowerCaseStr.Length, Me.editControl1.CurrentLine, col, Me.editControl1.CurrentLine)
`Selecting the text after converting to uppercase
Dim upperCaseStr As String
upperCaseStr = Me.editControl1.SelectedText.ToUpper()
Me.editControl1.SelectedText = upperCaseStr
Me.editControl1.SetSelection(col-upperCaseStr.Length, Me.editControl1.CurrentLine, col, Me.editControl1.CurrentLine)
