"Exception thrown: 'System.FormatException' in Microsoft.SqlServer.Types.dll " in ASP.NET console application C#

I am trying to insert a Sqlgeography column from latitude, longitude points to SQL server 2016 but I am getting

Exception thrown: 'System.FormatException' in Microsoft.SqlServer.Types.dll

I have already installed the Microsoft System CLR Types for SQL Server 2016 on the machine. What is the correct approach to resolve this issue.

SqlCommand addpoint = new SqlCommand("INSERT INTO " + Helper.TABLE_ALLINDEXPOINTS + "values (@id, @latitude, @longitude, @streetname, @longlat", sqlConnection);
addpoint.Parameters.AddWithValue("@id", id);
addpoint.Parameters.AddWithValue("@latitude",Convert.ToDouble(snappedPoints[j]["latitude"]));
addpoint.Parameters.AddWithValue("@longitude",Convert.ToDouble(snappedPoints[j]["longitude"]));
addpoint.Parameters.AddWithValue("@streetname", snappedPoints[j]["name"].ToString());
addpoint.Parameters.AddWithValue("@longlat", SqlGeography.STGeomFromText(new SqlChars(string.Format("POINT({0} {1})", snappedPoints[j]["latitude"], snappedPoints[j]["longitude"])), Helper.SRID));
addpoint.ExecuteNonQuery();

Error:

This is the table schema:

create table all_index_points
(
    id varchar(450) not null primary key,
    latitude float,
    longitude float,
    streetname nvarchar(max),
    longlat geography
);

Following are some of the things that needed correction in your code:

SqlCommand addpoint = new SqlCommand("INSERT INTO " + Helper.TABLE_ALLINDEXPOINTS + " values (@id, @latitude, @longitude, @streetname, @longlat)", sqlConnection);

Note the space before values. Also missing a closing bracket.

addpoint.Parameters.AddWithValue("@id", id);
addpoint.Parameters.AddWithValue("@latitude",Convert.ToDouble(snappedPoints[j]["latitude"]));
addpoint.Parameters.AddWithValue("@longitude",Convert.ToDouble(snappedPoints[j]["longitude"]));
addpoint.Parameters.AddWithValue("@streetname", snappedPoints[j]["name"].ToString());
addpoint.Parameters.AddWithValue("@longlat", SqlGeography.STGeomFromText(new SqlChars(string.Format("POINT({0} {1})", snappedPoints[j]["latitude"], snappedPoints[j]["longitude"])), Helper.SRID));
addpoint.ExecuteNonQuery();

Also do share the details of your exception along with the possible datatypes of your table fields in case the above does not solve your problem.

EDIT

Beside all the above mentioned problems the actual problem that you are facing will be solved by appending the following line before you call ExecuteQuery:

addpoint.Parameters[4].UdtTypeName = "Geography";

As SQL Server requires you to explicitly set UdtTypeName for parameter of type SqlGeography (and some other types as well, which I am not mentioning here).

So your updated code should look something like:

addpoint.Parameters.AddWithValue("@id", id);
addpoint.Parameters.AddWithValue("@latitude",Convert.ToDouble(snappedPoints[j]["latitude"]));
addpoint.Parameters.AddWithValue("@longitude",Convert.ToDouble(snappedPoints[j]["longitude"]));
addpoint.Parameters.AddWithValue("@streetname", snappedPoints[j]["name"].ToString());
addpoint.Parameters.AddWithValue("@longlat", SqlGeography.STGeomFromText(new SqlChars(string.Format("POINT({0} {1})", snappedPoints[j]["latitude"], snappedPoints[j]["longitude"])), Helper.SRID));
addpoint.Parameters[4].UdtTypeName = "Geography";
addpoint.ExecuteNonQuery();

Hope this solves all your problems.

Yet another side note is to use Helper.SRID = 4326 for the provided string format.
