title: Remove space dot(.) special characters from column name from excel to winform checkboxes
body: <p>Can anyone help me to solve the problem during upload a excel file to Winforms in C#?</p>
  
  <p>When I upload an Excel file, if any space or . or special characters (_,$,#) exist in an Excel column name (like "ORD. No" or DATE_JOIN, "emp name") then the column will display like "ORDNO" , DATEJOIN in C#.</p>
  
  <p>After uploading an Excel file, I just did following code to get the COLUMN NAME in checkbox with following code</p>
  
  <pre><code>for (int c = 0; c &lt; cnt; c++)
  {
      cbox = new CheckBox();//cbox checkbox object
      cbox.Text = ds.Tables[0].Columns[c].ColumnName.Trim();
  } 
  </code></pre>
