f I have a datatable in the following structure.

HostelName	    FloorName	FlatName	Occupied	Vacant
Building One	Floor A	        A	        2	       2
Building One	Floor A	        B	        0	       4
Building One	Floor A	        C	        0	       4
Building One	Floor A	        D	        0	       4
Building One	Floor A	        E	        0	       4
Building One	Floor B	        F	        0	       4
Building One	Floor B	        G	        0	       4
Building One	Floor B     	H	        0	       4
Building One	Floor B         I	        0	       4
Building One	Floor B         J	        0	       4

I would like to serialize it as a JSON object where the HostelName,FloorName & FlatName columns are the nodes in the JSON object like:

{
                "Building One": {
                    "Floor A": {
                        "A": {
                            "Occupied": "2",
                            "Vacant": "2"
                        },
                        "B": {
                            "Occupied": "0",
                            "Vacant": "4"
                        },
                        "C": {
                            "Occupied": "0",
                            "Vacant": "4"
                        },
                        "D": {
                            "Occupied": "0",
                            "Vacant": "4"
                        },
                        "E": {
                            "Occupied": "0",
                            "Vacant": "4"
                        }
                    },
                    "Floor B": {
                        "F": {
                            "Occupied": "0",
                            "Vacant": "4"
                        },
                        "G": {
                            "Occupied": "0",
                            "Vacant": "4"
                        },
                        "H": {
                            "Occupied": "0",
                            "Vacant": "4"
                        },
                        "D": {
                            "Occupied": "0",
                            "Vacant": "4"
                        },
                        "I": {
                            "Occupied": "0",
                            "Vacant": "4"
                        }
                    }
                }
            };

int i=0;
StringBuilder sbJSON = new StringBuilder();
datatable dt;
sbJSON.Append("[");
if(dt.Rows.count>0)
{
foreach (DataRow dr in dt.Rows)
{
sbJSON.Append("{\"" + dr[0] + "\": ");
sbJSON.Append(",\"" + dr[1] + "\": ");
sbJSON.Append(",\"" + dr[2] + "\": ");
sbJSON.Append("\"" + dr[3] + "\",");
sbJSON.Append("\"" + dr[4] + "\"},");
}
sbJSON.Remove(sbJSON.Length - 1, 1);
}
sbJSON.Append("]");

result = sbJSON.ToString();
