c# - How to declare string with value from other form -
what trying value of uid mainform , declare level in form1.
mainform
using system; using system.collections.generic; using system.drawing; using system.windows.forms; namespace sof_op_center { public partial class mainform : form { public mainform() { initializecomponent(); error.visible = false; } void loginclick(object sender, eventargs e) { if (agent.text == "user" && aid.text == "pass") { this.hide(); form1 frm = new form1(); frm.show(); } else if (agent.text == "user2" && aid.text == "pass2") { this.hide(); form1 frm = new form1(); frm.show(); } else { error.visible = true; } } } } form1

you can define constructor form1 take string , pass uid value when in mainform:
form1:
public partial class form1 : form { string level; public form1(string uid) { level = uid; initializecomponent(); } } mainform:
public partial class mainform : form { string uid = "uid"; public mainform() { initializecomponent(); } void loginclick(object sender, eventargs e) { var frm = new form1(uid); this.hide(); frm.show(); } }
