How to change the DataTable Column Name?

I have one DataTable which has four columns such as

 StudentID        CourseID          SubjectCode            Marks    
------------     ----------        -------------          --------
    1               100              MT400                  80
    2               100              MT400                  79
    3               100              MT400                  88

Here I am inserting this Datatable into the Sql server table by passing this datatable as an XML Table.

I just want to Change the DataTable Column Name "Marks" as "SubjectMarks" and pass this DataTable as an XML Table.

I know how to pass the DataTable as an XML Table. But I dont know, How to change the DataTable Column Name "Marks" as "SubjectMarks".

after generating XML you can just Replace your XML <Marks>... content here </Marks> tags with <SubjectMarks>... content here </SubjectMarks>tag. and pass updated XML to your DB.

Your XML Generate Like as below.

<NewDataSet>
      <StudentMarks> 
          <StudentID>1</StudentID>
          <CourseID>100</CourseID>
          <SubjectCode>MT400</SubjectCode>
          <Marks>80</Marks>
      </StudentMarks>
      <StudentMarks> 
          <StudentID>1</StudentID>
          <CourseID>100</CourseID>
          <SubjectCode>MT400</SubjectCode>
          <Marks>79</Marks>
      </StudentMarks>
      <StudentMarks> 
          <StudentID>1</StudentID>
          <CourseID>100</CourseID>
          <SubjectCode>MT400</SubjectCode>
          <Marks>88</Marks>
      </StudentMarks>
  </NewDataSet>

Here you can assign XML to string variable like as

string strXML = DataSet.GetXML();

strXML = strXML.Replace ("<Marks>","<SubjectMarks>");
strXML = strXML.Replace ("<Marks/>","<SubjectMarks/>");

and now pass strXML To your DB.

Use:

dt.Columns["Name"].ColumnName = "xyz";
dt.AcceptChanges();

or

dt.Columns[0].ColumnName = "xyz";
dt.AcceptChanges();
