Cannot implicitly convert type ‘string’ to ‘System.Windows.Forms.DataGridViewTextBoxColumn

When developing a .NET application (i.e. in C#), under certain circumstances, you might get the error message: Cannot implicitly convert type ‘string’ to ‘System.Windows.Forms.DataGridViewTextBoxColumn

Why you got the implicit conversion error

If you get the above error, then you have most probably set as a column name for one of your datagridview column the reserved word ‘name‘.

If you do this, then the compiler finds a conflict between the assignment of the form’s name and the DataGridview’s column name.

How to resolve the issue

To resolve this issue just change the name of the DataGridView’s column to something else instead of “name”.

There is a reason there are reserved words not only in .NET byut in many other development platforms as well (i.e. SQL Server, etc.).

To this end, please make sure that you are not using any reserved words in your development work because if you use them, there is always the risk of a conflict with system routines like the above example.

Check this MSDN article for information about the words reserved by the linker.
