You can use below Helper function for your requirement

for this namespace system.Data Required

//Add following namespace in namespace section

using system.Data;

//below is the helper function which will take input as a path of your file and will return you datatable

C#

public DataTable ConvertToDataTable(string path)
		{
			string s = string.Empty;
			string[] stringarry=System.IO.File.ReadAllLines(path);
			System.Data.DataTable data = new System.Data.DataTable();
			data.Columns.Add("Type", typeof(string));
			data.Columns.Add("Category", typeof(string));
			data.Columns.Add("Grade style", typeof(string));
			data.Columns.Add("Random answers", typeof(string));
			data.Columns.Add("Randomize Options", typeof(string));
			data.Columns.Add("Question", typeof(string));
			data.Columns.Add("A", typeof(string));
			data.Columns.Add("B", typeof(string));
			data.Columns.Add("C", typeof(string));
			data.Columns.Add("D", typeof(string));
			data.Columns.Add("E", typeof(string));
			data.Columns.Add("Correct", typeof(string));
			data.Columns.Add("Points", typeof(string));
			data.Columns.Add("CF", typeof(string));
			data.Columns.Add("WF", typeof(string));
			data.AcceptChanges();

			DataRow dr=null;
			foreach (string st in stringarry)
			{ 
				 if(!string.IsNullOrEmpty(st))
				 {
					string[] splitarray=st.Split(':');

					if (splitarray != null && splitarray.Length > 1)
					{
						if (splitarray[0].ToUpper() == "(Type)".ToUpper())
						{
							dr = data.NewRow();
							dr["Type"] = splitarray[1];
						}
						else if (splitarray[0].ToUpper() == "(Category)".ToUpper())
						{
							dr["Category"] = splitarray[1];
						}
						else if (splitarray[0].ToUpper() == "(Grade style)".ToUpper())
						{
							dr["Grade style"] = splitarray[1];
						}
						else if (splitarray[0].ToUpper() == "(Random answers)".ToUpper())
						{
							dr["Random answers"] = splitarray[1];
						}
						else if (splitarray[0].ToUpper() == "(Randomize Options)".ToUpper())
						{
							dr["Randomize Options"] = splitarray[1];
						}
						else if (splitarray[0].ToUpper() == "(Question)".ToUpper())
						{
							dr["Question"] = splitarray[1];
						}
						else if (splitarray[0].ToUpper() == "(A)".ToUpper())
						{
							dr["A"] = splitarray[1];
						}
						else if (splitarray[0].ToUpper() == "(B)".ToUpper())
						{
							dr["B"] = splitarray[1];
						}
						else if (splitarray[0].ToUpper() == "(C)".ToUpper())
						{
							dr["C"] = splitarray[1];
						}
						else if (splitarray[0].ToUpper() == "(D)".ToUpper())
						{
							dr["D"] = splitarray[1];
						}
						else if (splitarray[0].ToUpper() == "(E)".ToUpper())
						{
							dr["E"] = splitarray[1];
						}
						else if (splitarray[0].ToUpper() == "(Correct)".ToUpper())
						{
							dr["Correct"] = splitarray[1];
						}
						else if (splitarray[0].ToUpper() == "(Points)".ToUpper())
						{
							dr["Points"] = splitarray[1];
						}
						else if (splitarray[0].ToUpper() == "(CF)".ToUpper())
						{
							dr["Correct"] = splitarray[1];
						}
						else if (splitarray[0].ToUpper() == "(WF)".ToUpper())
						{
							dr["WF"] = splitarray[1];
							data.Rows.Add(dr);
						}
						
					}
				 }
			}
			data.AcceptChanges();
			return data;
