                SemesterCode = "Summer",
                Year = DateTime.Parse("2019-08-01")
            });

How I Put Data in Json FIle for ComplitedSemister property ? I get an error that Name ,Instructor, Credit can't access. But Other property also accesss and work properly

You need to create the appropriated object

List<students> _data = new List<students>();
            _data.Add(new students()
            {
                ID = 101,
                fName = "Kamal",
                mName = "Hasan",
                lName = "Fahem",
                Dept = "CSE",
                Degree = "BSC",
                  // Create the Array and populate with the object
                  ComplitedSemister = new _Semister[]{ 
                  new _Semister()
                  {
                      Name ="dsg",
                      Instructor ="Jamal",
                      Credit =25
                  }},

                SemesterCode = "Summer",
                Year = DateTime.Parse("2019-08-01")
            });

You declare ComplitedSemister as an array of _Semister:

    public _Semister[] ComplitedSemister { get; set; }

then you try to assing as a single object:

              ComplitedSemister =
              {
                  Name ="dsg",
                  Instructor ="Jamal",
                  Credit =25
              },

so it fails

I prefer using List when is possible

 public List<_Semister> ComplitedSemister { get; set; }

then

ComplitedSemister = new List<_Semister> {{
                  Name ="dsg",
                  Instructor ="Jamal",
                  Credit =25
              }},
